Is there a radio harness available for 99 996 CR220

I'm looking at replacing my CR220 radio with an aftermarket radio ... considering an Alpine CDA-9887. I spoke to the folks at Best Buy and Circuit City and they stated that they'll have to splice into the existing radio harness to accomodate the radio. I was rather surprise to hear that considering plenty of harnesses available for many vehicles. I did a search on eBay to see if there are any available, the only ones I can find are for 1996-1998. I have a 99 C2 and would like to avoid splicing into the existing wiring as much as possible. Thanks.

The CR220 sucks.

Hence the reason why I posted the note in the forum ... looking to replace the HU and seeking a harness. It seems that there may be a harness for Audi/Volkswagen that may be compatible. I found an article on Renntech on a Pioneer installation. http://www.renntech.org/forums/index...pic=10095&st=0 The harness for the Audi/Volkswagen is available on eBay .. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=014&sspagename=STRK%3AME WA%3AIT&viewitem=&item=330176970171&rd=1

yup, you will use a VW harness. Plug and play for the most part. Don't forget an antenna adapter as well.

Anyone have the part number for the VW/Audi harness?

70-1784

Thank you sir!

Hi Folks, I finally received my Alpine CDA-9887 receiver and VW harness. Before I start on my HU replacement and splicing into the wiring harness, is there a wiring diagram on the forum I can use as a reference. I recall seeing one a while back but could not seem to find it now. Can someone please point me to the diagram ? I have a 99 C2. Thanks in advance

if you purchased the correct harness, the installation should be straightforward. the harness should plug into the car's existing plugs and have the wires on the other side color coded for DIN radio installs. if so, then all you need to do is match color for color

The concern i have is that it is a VW harness and the colour code may not match up to the Porsche wiring.

understood. unfortunately I'm not familiar with the VW harness. however, as DJbrand1 mentioned, it should be plug and play. I did look at the link for the harness on ebay, and it does use the same plugs as Porsche. I'd be willing to bet that VW and Porsche use the same parts-bin-engineering approach and share this part. (considering how much of VW is owned by Porsche ) so it should have the same wiring scheme as the one for your 996

The colors of the wires in the harness seldom actually match the colors of the vehicle's wire harness. Don't let that scare you.

yup, and that's the whole point of a converter harness such as this. however, I can understand rlim just wanting to be sure, just in case the VW factory harness may have a slightly different pinout than the Porsche harness even though the plugs are the same

Rlim, i had the same issue as you did. i tried calling places, even crutchfield, and they didn't have the plug. I got a plug that didn't even fit. I was afraid to try any other plug just in case the wirings didn't match. I got the alpine 9885 from cruchfield that came with free Ipod cable ($30.00). I tapped each wire, and ran RCA cables to 2 new amps (1 for subwoofer behind my back seats and the other amp for speakers). I spliced the speakers in the front of the car and ran them to the amp. I didn't wanna use the factory amp as it was not powerful enough. The sound is amazing and great and it hits pretty hard. I can post pics later. The only thing i didn't plug in to the stereo was the Light wire, i like my stereo bright all the time. Also i ordered the Aux cable from cruchfield ($15.00) so i can plug in my mp3 player or other aftermarket mp3 player using a stereo cable.

I installed an Alpine 9835 in my BMW and it was a straight forward installation as the harness wiring are color coded correctly. I had a similar setup where I had a mono sub amp and 4 channel speaker amp installed in my trunk. I eventually removed it as I needed the space in my trunk ... Dual 12" sub box took all my trunk space. I ended up using the Alpine HU with the Harmon Kardon system that came with the car. The sound quality is quite good surprisingly.

To my disappointment, the Metra Wire Harness (70-1784) for VW/Audi which I thought would be a direct plug-in to the Porsche radio harness is incompatible. It seems that I will have to splice into the radio wire harness after all. I’m hoping someone can let me know the radio wire pinout/colour coding. I’ve attached a couple of pictures of the radio harness and the Metra harness. Thanks in advance.

I was in the same boat exactly - but bought the Metra 70-1787. I'm still installing but it looks like it's the right harness...

The harness with the black connector plugs in. However, the connector (blue/green/yellow) does not. As you can see in the pic, there are many more pins on the coloured connector to the Metra which only has 6 pins.

the 70-1787 has another connector which fits the multi colored one - and has two sets of rca connectors that your stereo plugs into... http://enfigcarstereo.com/shopsite_s...rce=googlebase

The red part of the metra connector connects to the three part blue/yellow/green plug and the other part of the metra harness (black) contains the power components - pretty straightforward.

I too, used the 1787 harness. I have an 02 C4s with the bose system. Unfortunately the Bose amps seem to only take line level inputs...hence the RCA plugs on the harness were useless. I still had to splice the speaker line outputs into the factory wiring. the rest of the plug worked fine.

SeattleDL, In looking at the 70-1787 harness, there are RCA plugs attached to the connectors. Did you use them or remove them and splice them into the aftermarket radio harness? Were you able to complete the installation of your radio? Thanks for your direction and help.

I used the RCA connectors and didn't have a problem - there were two sets of preouts from the back of the DNX7100. System is up and running now. I didn't look to see which amp I have - but I have an '01tt that came with Nav. happy to help - the only way I was able to get mine set was with help from the forum.

I will look into 70-1987 harness. There are preouts on the Alpine unit which I'll use. Truely appreciate you help and guidance .. Thanks

Does anyone have the antenna adoptor part number by chance. Thanks in advance.

Quote: Greetings: I'm in the process of working on an install in a '02 996 Cab with the Bose (no hifi) system and factory C220 head unit and factory changer. In the dash, there are THREE plugs for the C220. one black as shown above, one brown that is similar in shape to the black one, and the red/yellow/green like above. I believe in this situation (which may be similar to yours), splicing into the factory harness can be eliminated by using portions of both the Metra 70-1784 and 70-1787. I'll explain. The black plug for the 1784 has pinouts for all of the speaker wires. The black plug for the 1787 does not have pinouts for all of the speaker wires. Most of the pins areas in that plug are blank, so the factory speaker wires get no signal from the 1787's black plug. And since the 1784 has no red plug for the red/yellow/green factory plug to connect to, the factory amp gets no turn on signal/audio signal. I believe the solution is to use a combination of the 1784 AND 1787. Meaning, utilize the black plug from the 1784 in combination with the red plug from the 1787. The blue wire that connects the red plug to the black plug in the 1787 kit, would be cut from the black plug, and spliced into the blue amp turn on wire located on the black plug of the 1784 kit. The RCA's on the red plug of the 1787, would theoretically either not connect to anything, or connect to the RCA's exiting the aftermarket head unit. In my case, the Avic D3. My hypothesis is this will solve the issue, but havent had a chance to test yet. Thoughts anyone?

that is actually exactly what i ended up doing. I started by using the 1787 as a whole, but needed to use the 1784 piece to get the power to the amp. Figuring that piece out took me a little bit... I used the RCA's from the aftermarket head unit. so the approach that worked for me was to buy both harnesses, just as you say. I wish I'd been able to think it out ahead of time like you did though. The only other thing I ran into as I put things together was that you have to be careful not to get the constant power and the ignition dependent power wires mixed up. I think they are in different locations in the 1784 and 1787 harnesses.

Seattle: Thanks for confirming. Oh, it took me several HOURS to think this through, and if it wasn't for this thread and it's pics, and reading it over and over, I most likely would not have even thought about using the two harnesses. What is frustrating is how I apparently didnt use specific-enough search terms to get to this thread (actually this forum) until days after beginning the initial project planning. This site has much more info than the renntech site. I actually JUST found this thread, which is somewhat helpful as well, but looks like he didnt know about the proper harnesses. http://www.renntech.org/forums/index...pic=10095&st=0 And thanks for the heads up on the possible power wire issue. I'll be on the lookout for that. Question: I assume you also had 3 plugs going into the back of your stock headunit as well? The green/yellow/blue plug, the black plug, AND the brown plug? In some of the posts, many appear to not have the brown plug. Does the brown plug mean it's a Bose Hifi system? And lastly, did you have to utilize the RCA's on the 1787 in your setup? The Avic-D3 that Im installing has RCA outs, and Im assuming I will connect those to the 1787's RCA's. Placing the following terms in so that others who search can find this thread and have some help. Avic-D3, Double Din install in 996, Double Din Install in Porsche, Metra Harness Porsche 996.

Great idea to put the search terms in the thread. Here's a pic of what I had. Mine came with Nav. I didn't use the two connectors on the bottom of the picture(larger blue and black ones with the grey clamps). I did use the rca outs from the DNX-7100 without a problem. It sounds though like the RCA outs may not work on every system? But at least in my situation it wasn't a problem. I'm not sure about the differences between the brown plug you have and the ones I have. I assume that either the blue or larger black one is from the nav, but would have to check the wiring diagram...

Thanks for the response. The 996 Im working on doesnt have those plugs with the white "clamps" on them. Im guessing thats NAV related. I see you also that your factory wiring harness doesnt include the brown plug that I am working with. And the brown plug (if I am recalling correctly) is the one that has all of the speaker wires in it. So Im thinking the RCA's wont be used in this my instance. Well, once the 1787 arrives and I get back to the project, we'll see how things go. I'll update the thread once things get back on track. Thanks for all of the info.

Project completed. Avic D3 installed. And you were correct, the Switched hot and constant hots needed to be swapped. In the 996 wiring harness, the solid RED wire is constant hot. The Yellow is the switched hot. On the metra harness and the avic harness, its the other way around, which is odd. (RED for switched/yellow for constant). The brown and black plugs that used to plug into the Porcsche head unit plug into the metra 1784. (THe brown plug carries all of the speaker wires for the porsche). The red plug from the 1787 kit plugs into the blue/yellow/green plug from the Porshe, and the blue/white wire from the 1787's red plug, taps into the blue/white wire from the 1784/Avic harness. (The blue white is the amp turn on wire). Did not need to use the RCA plugs. Voila. Thanks for all of the assistance.

Installation with the 17-1787 worked on mine. Even the DSP functions work!

Is the air / heat controller hard to move to the bottom ? I have a 996 C4 and I just purchased a Pioneer D3 - I was planning to install the unit on the 2 bottom slot so I do not have to move the air / heat controller - The only installation I have seen has the Avic d3 on top and he air controller on the bottom - Does anybody has an image of the installation?

I also installed the Avic-D3 and relocated the AC controls to the lower console... the only hard part was getting the AC wire harness rerouted to reach the new location. It is a bit of a hassle but manageable. I removed the side panels on the passenger footwell to get more access. The rest was pretty easy. David

I finally completed my Alpine 9887 installation. I've used only the 1787 harness kit with the RCA plug which plugs into the HU and works fine. The sound quality is not anywhere I expected ... using the existing stock amp and speakers. My Beemer sounded much better with the Alpine as I think the Harmon Kardon amp and speakers are much better than the stock Porsche amp and speakers combination. Well, I'm now considering bypassing the stock amp and connecting directly to the speakers. I also have a pair of Infinity Reference 5.25" components which I can use. The 5.25 " woofer is a direct swap with the door speak, however the tweeter is a problem as I am unsure where to place them without having to drill into the door or windshield pillar. Another option is replacing the dash speakers with component 4" speakers... which I'm quite hesitant having to swap out the speaker, hence breaking into the speaker housing. Any suggestion on speakers ? I'm trying to retain the stock look as much as possible. Thanks

I did a seach as majority of folks went with Focal for the fronts and some suggested getting a 3-way passive crossover and connecting the 6.25" door woofer, 4" mid, and tweeter in the dash. I'll look into doing the same .. time to do some eBay search for 3-way crossover and 4" component speakers. I'll reuse my Infinity 5.25 for the door..

Thanks Reborn 996 ! I just finished installing the Avid D3 with XM and Ipod adapter - Can I ask where to buy the frame that would go around the Pioneer D3 and fill up the space between the unit and the dash ? I think I found the frame around the air conditioning at Pelikan parts Thanks

I used a Kenwood faceplate as it has a larger front face that fills in the entire area on the outside of the radio in the Porsche dash. You have to trim it however but that is not hard to do. The Pioneer one does not have enough material on the edges to fill in all the way. I got the Kenwood faceplate from Rod at Car Audio Innovations but I think Kenwood sells them online as well. David

Are you selling your cdr-220? My is in need of a facelift. Thanks, Jason

Hi Jason I suppose you are talking to me - Well What is the value of that magnificent :-) unit ? Paolo

$100.00 + shipping would be a nice price for me.

guys, can someone please explain simply which harness (between the 1784 and the 1787) provide which functions? in other words, i've gathered the 1784 provides the speaker function. anything else? what does the 1787 provide? i've hooked everything up as i "thought" it should be, but i get no power to the Kenwood DNX-7100. I had this all working before, but it was spliced directly (no Metra harness). the only thing i've got in the 1784 right now are the speaker connections. everything else goes to the 1787. i've crossed the red/yellow wires on the 1787. am i missing something here? thanks for any help... josh

never mind... it just takes me longer than most sometimes ;-) ...josh Quote:

I have the hi-fi option (door subs) but no Bose - all stock. Can I use these adapters, and if I do, HOW do I use them? Thanks! Andy

You want the adapters from Midwest.....IM NOT ASSOCATED WITH THEM http://www.midwestelectronics.com/bl...88e4bedb2b4d96 this adapter replaces the output to the 6CH amp in the front of the car...they have all you need...its all listed as Blaupunkt....as the Harmon/Becker Group ownes all 3.
