power mirror install help

[alexlitov]

Hello Everyone. I just ordered a power rear view mirror for my P5. I'm wondering where can i splice into the wiring. I need a + and a -.

Thank you in advance. The mirror is in the mail.

If you need a constant "always on" power source, you could tap into the map lights in the overhead console. If you need "switched power" you could tap from the moonroof power source if your car is equipped with one. These are probably the best ways to do this without having to run a rats nest of wires all over the place.

You don't need a - wire. Bare metal is what you should use.
