Where to Access Brake Light Switch Signal on 1995 Chevrolet C/K Series Pickup

Question:

I’m working on a 95 Chevy 3500 installing a brake controller. I’m trying to find a brake hit signal. I usually go off of the brake switch on the pedal but in this truck the brake switch is very difficult to get to. Is there another way to find a brake hit. Thank you

You can use any access point to the brake light circuit on your truck as the activation signal for a trailer brake controller. Usually the brake pedal's brake light switch (the cold side of it) is the preferred way to get an electrical brake signal for triggering the controller. Sometimes on newer vehicles a 3rd brake light's wiring can be easier to find.

Often the wire at the brake switch you need is white, but it can be yellow on some model year. In the linked video showing a 1997 it is a white wire.

Another way is to use a fuse tap # F2526 in the circuit for the brake lights to give you access to the brake signal. This is okay so long as that circuit carries ONLY the brake signal.
