Installing Curt Venturer Trailer Brake Controller # C74VV in 1994 GMC 3500 C/K Series Pickup
Updated 05/30/2014 | Published 05/29/2014
Question:
I know how to hook up everything except the line to the brake useing 51515 pigtails. I can feel the wires going the the brake switch. Is there a easier wire to find that by the switch?

Expert Reply:
If you cannot access the wire going to the hot side of your brake light switch you may be able to access the brake pedal switch signal at an electrical box located near the emergency brake pedal. If you can find in this box a terminal(s) labelled NAT this might provide an alternative means to obtain the signal. You can use your circuit tester on this pin to confirm that it carries a signal ONLY when the brake pedal is pressed (and not when other vehicle functions are activated).
I have linked a photo to help illustrate this box and the NAT pin.
Once you have your brake signal wire, this will connect to the red wire on your Venturer brake controller.
