Installing a Backup Sensor
I'm trying to install one of these in my '01 A4 1.8T:

It hooks into the reverse wire so it knows to turn on when you're backing up. Then it beeps when you get too close to the next car.
Has anyone installed a device like this? Where can I find the reverse wire in the trunk? Also, is there any way to get the wiring from the device into the trunk without drilling?
TIA,
Jeff
