Why not make it very easy on yourself and just tap into the +12V from the cigarette lighter outlet? Seems as if you are overly complicating the install. You can also tap directly into your fuse box for an ignition switched power source. Radio Shack sells fuse taps for exactly this purpose.
Hope this helps!
On BMW's the 12v wire that is only active when the car is on, is a green wire with white stripe. Not sure about the Audi though, might be the same.
Thank you JeffOriginally Posted by Jeff E39
I'll try this wire :wink:
In fact, I want to mount it high, near the internal lighting, so it's easier for me to connect it on the 12V ligthing :wink:
Be careful though, just because it works on the BMW doesn't neccessarily mean it will work on the Audi. You might want to consult your dealer b4 hand as well.Originally Posted by Lionel996
surely
I'll test this wire with a small light and a fine wire connect on a "ground" and the other wire on the green/white connector
My experience with Audi's and V1's, since there a few in my family. Is that most of the time they hardwire through the dash vs. the overhead light.Originally Posted by Lionel996
Should be the green/white... 12v ciggy lighter is easier dont gotta worry about anything.
Do yourself a favor and borrow/buy a cheap DVM and just measure the voltage...
