V1 install-Switched Pwr Source in RearView Mirror?

[1080iAddict]

I am about to embark on my V1 installation design criteria. Here is my plan. I would like to install the V1 under the rearview mirror. I have the self-dimming rearview mirror. When the ignition key is removed, the small power light in the mirror goes out. When the ignition key is inserted, the small power light in the rearview mirror goes on. What does this tell us?

Well, it tells us there is a switched power source in that mirror that travels down the wire stalk from the headliner to a plastic cover thing. That plastic cover thing has the white LED that illuminates the interior of the cabin (well, supposedly illuminates anyway). Then there is a separate small wire stalk that travels to the mirror. I think i can remove the plastic cover in between the two wire stalks and access the wires in there and meter the wires to find the switched power source and the ground. If that switched source is 12 volts, we just may have found a new V1 install design. There would be no visible wires save the 2 inch run from the V1 to the plastic thing.

I did this in the M5 and it worked. Same theory applies here. In theory.

Thoughts on this approach?

Porsche has published a 997 Service Manual but it is anywhere but complete. Many sections are still missing including the wring diagrams. The best we could hope for is that it is the same or similar to the last 996's.

If it is like the 996 then you should need to take the mirror but the roof console will need to be opened, Generally Porsche uses brown colored wires as ground and the last 996's (2005) used black/orange for power.

Thanks, that's a start. I am going to gently try and unsnap that plastic housing behind the rearview mirror and hunt for those colored wires.

Loren,

Two quick questions:

1. Do you know if the plastic assembly behind the rear view mirror simply unsnaps if i pull the sides hard enough or if i put a straight edge in the crease to separate the sides? It's on there incredibly tight and I do not want to break it.

2. If I wanted to remove the interior cabin light clear plastic assembly at the headliner, do I simply pull it down from the windshield side, i.e., if one were to change a bulb up there? It too is held on incredibly tight.

I want to search for wires in those locations to measure for switched 12 volts. This car is put together real tight and I am nervous to take these steps without asking first.

Thanks!!

Sorry, I haven't tried that on a 997 yet. The service manual (as expected) does not have that part yet. I think your best bet is to follow the bulb change instructions in the owners manual and then look to get the cover off. Then perhaps you can see how the rest is removed.

The OM has no info on changing bulbs in that area. Thanks anyway.

I see the roof console bulb change on page 232 of the owners manual.

My manual has tire pressure information on page 232. (2006 997S owners manual)
