Brake Controller Wiring on a 1999 Chevy Suburban
Question:
I have a 99 Chevrolet suburban which is the old-style suburban that they made from 92 to 99. This did come with the trailer towing package, but still needs the controller hardwired. This is the one that doesnt have any adapter listed. I was able to find the orange and blue wires tucked under the under hood fuse box. These wires run to the rear of the vehicle. My problem is trying to figure out the wire to use from the brake light switch. It is very difficult under the dash to see the brake light switch. There are several wires bundled together that probably come from the switch. Do you have any tips on how to locate the wire? I believe one of these wires also goes to the transmission and I do not want to tap into the wrong wire. What color should the wire be?

Expert Reply:
Most vehicles actually have two wires attached to the brake pedal and the stoplight switch. The easiest place to access the wire and test to see which one you need to connect to is right in that area. Once you determine the correct wire you can then follow it up behind the dash and the connection there if so desired.
