Where do I run a wire through the firewall(s)
I know some of you have had to run a wire for (foglights etc) through the A4 firewall(s). Where's the best place to run the wire through, and how do I find it?
Thanks (searched the archives, but there was only one post about the vacuum line) Antony |
Depends on the year
Some have a grommet to the right of the battery (see pics).
If you don't have that, you can run through ECU box, but I don't recommend this for power wire for an amp, but it's fine for boost line. <img src="http://24.26.38.255:8080/audi/boostguage/rear_firewall_grommet.jpg"> |
Run the wire(s) in and out from the ECU box.
|
Try going through the ECU housing.
If you're facing the front of the car, there's also a rubber grommet left of the steering wheel column to run wiring through as well.

Thanks for your help. I'll start looking...!
