Picture request: E30 O2 sensor routing
« on: January 01, 2013, 01:46:22 PM »
This may sound funny, but since my car was never originally a M42 car I have no idea how the O2 sensor is routed. Now that I am wiring that part of the standalone....I need to know how the proper routing goes so I can use the correct wire lengths.

If anyone can give a picture of the general routing on the firewall that would be great. Thanks!

I don't have a pic, but I ran mine behind the heat shield. It hooks up under the battery tray to the engine wiring harness. My car was formerly M10.
