alright im about to start tubbing my firewall on my 1994 gmc sierra for 22's but i would like to see where you guys have relocated the wiring harness on the drivers side on the firewall. ive already moved it up as far as possible, but its not enuff.
any help and photos would be appreciated.
i'm about to do that myself, you have to move it under the brake booster, there's no room for it to go above the tire with even 20's. I've also seen it come through on the pass side pretty close to the engine. Maybe this thread will help a little. It shows the wiring harness coming out the passenger side.
