The A-pillar cladding is flexible, so I ran the power for my detector from the connector in the lower console as Hurdi referenced, along the underside of the dash above the passenger footwell, around the edge of the dash (between the dash and the passenger door, along the edge of the dash to the A-pillar, up the A-pillar, and inside the front of the headliner to the rearview mirror.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

13 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I searched... cant find the answer... I had a bookmark before my pc crashed to an instruction page on a v1 hardwire to the sunroof motor or dome light does anyone here happen to know what wire I need to look for in there? thanks

POST 2 / ORIGINAL POSTEROriginal post

No one?! found a bit about unswitched power from the map light - brown - and red/black is + hoping for a switched source in there....

POST 3Original post

I think in that area the Pos will be a light brown wire w/ a green stripe and ground will be red wire w/ black stripe. Or you could do what I did and delete or tap into the LED that shines down from the mirror mount. (search Passport 9500 hardwire)

POST 4 / ORIGINAL POSTEROriginal post

installed it last night and gave up on it being switched... I did reverse the polarity somehow - thanks medtech for the correction.

POST 5Original post

it is either the red of the green wire.... if you cut the wrong one the car will have immediate IMS failure.. No pressure.... Just pick one.

POST 6 / ORIGINAL POSTEROriginal post

Sharky - covered by warranty due to 1 previous failed IMS so no worries...

POST 7Original post

theres a wire but I dont remember what color. It will dim off after a few seconds you turn off key. It is the same wires as the dome lite that dims off.

POST 8 / ORIGINAL POSTEROriginal post

Ye the light dims but the power is still there... anyhow install is done... no more dangling wire to splitter on cig lighter... Also semi hard wired the navi... major annoyance now resolved.

POST 9Original post

My 2009 997.2 911 S was delivered years back with a variable (powered) mirror by mistake. It was not connected to the harness and the outside mirrors were the standard, non-variable type. The dealer offered to swap it for a manual mirror, but I declined as it is a nice option I have had in two BMWs. I've waited 'till the car was off warranty (OK, quite a bit longer) to fool with the electrical system and so would also like to know what wires in the front interior "dome" light area are switched on/off with the key? Thanks

POST 10Original post

Why would you use a pick up from the dome light? There is a switched power source by your right leg. Behind the pull off triangular padded panel. Half of that plug you will find hanging inside, is switched as the ignition comes on. The other half is on all the time. I picked up the switched part in there for my radar and my GPS. NOW, Both the GPS and the Radar detector come on and off with the ignition switch.

Depends on where you need power. If you're putting in a powered mirror (auto dim, Homelink, etc) on a coupe, it's easier to draw power from the dome light and/or sunroof.

POST 12Original post

The A-pillar cladding is flexible, so I ran the power for my detector from the connector in the lower console as Hurdi referenced, along the underside of the dash above the passenger footwell, around the edge of the dash (between the dash and the passenger door, along the edge of the dash to the A-pillar, up the A-pillar, and inside the front of the headliner to the rearview mirror. No holes drilled, no need to detach any trim panels, and no visible cabling. This picture was taken when I hadn't yet finished tucking the cord behind the leading corner of the A-pillar trim, so there's still a bit of visible cable... I have since adjusted the wire as it comes down the rear view mirror mount so it's more flush / less visible.

+1 I tapped into the wires by the dome light for my Homelink dimming mirror.
