Electrical woes where to start T/S

I have the computers out of the car dme/alarm/airbag but the dash odometer/rpm/time digital display lights stay on after I pull out the key all the idiot lights are off..I would not think that the computers would cause this, also can the car be turned over without the computers? Anyone have an idea where to start trouble shooting. I have the tech manual. As an added there is no power to the windows but if I jump power to the switches the window work. Logical guessing is allowed here.

the back lighting stays on for 10 minutes or so anyway, but if its longer then that, try un pluging the ign switch and seeing if they go out. It may need to see the alarm ecu to shut off the cluster. can the car be turned over sure............. all you have to do is jump 12v+ to the small termianl on the starter it will crank but not fire i dont have diagrams at the house but if you have diagrams look for where the power should come from for the windows

Thanks firehawk: Yes I did try for 10 mins and still on. Yes, I removed the ignition switch and the digital dash lights stayed on? I would have thought that the power for everything came from the ignition switch to begin with. I have voltage at the fuse for the windows will have to look at schematics. I was hoping to crank engine using the ign switch without computers in. I am just trying to pretest before installing computers/controllers and avoiding burning them out, so knowing what should work without comps is helpful. What works 1. lights ok 2. horn ok 3. hazard sort working of I am missing tail lights bulbs so trun signal will not blink 4. gauges registering ok 4. Power to lighter 12V 5. windsheild wipers ok 6. Climate control lights ok 7. Liscense plate light 8. Emergency idiot brake light What does not 1. windows 2. sun roof 3. turn signals-no tail light bulbs 4. Does not have air bags 5. Spoiler - but I can hear the relay click when I operated the switch on fuse box 6. No Start/Cranking 7. Stupid, but I do not know how to open the gas door is this electric?

Cranking is controlled by the DME. The ignition switch start position is a 'suggestion' to the DME. Bill

It's looking like I need to install the controllers/comps for the rest to operate.

What MY car is it?

2001 996 C2 coupe manual does that help?

whats the history of this car?

If it was a 2002 or newer I was going to ask you to look something up for me, since it's all apart. Bill

To much history to mention since I have been working on it.

I do not know how much difference there is, but if you need a schematic of your year car let me know.

What I need is any part numbers that might be present on the DME connectors on the wiring harness. But a 2001 has a different setup. Bill

OK gotch cha

Just put an whole ignition switch (the pistol) in it and call it a day. Easy fix

Bin there done that. It is easier to actually remove the connector at back just to see if the lights go off which they did not.

the alarm control is whats going to shut off your cluster, atg least thats how i remeber it, i really dont have to work on to many eraly 996s these days and things start to blur. You really need to get a dme and alarm ecu into the car to test anything else. I Will tell you to check the grounds under the driver seat they are often damaged and or left off when people work under there and when you say that your alarm ecu is missing it tells me someones been there. I have seen those grounds do really weird things with the windows and the top

I think you are correct time to install the computers, I did check thouse grounds and cleaned as needed it's rather nice my whole interior is out so I can see the ground points. I'll add to this tread when everything is installed.
