Brake signal for trailer tow controller

[Aruba1]

Guys, I have a 1972 GMC C20 that I want to install a brake controller for the electric brakes on my trailer. Where is the brake signal? Any pics, video and/or instructions? I can't find anything on the search fuction, maybe we need to ban it from this site, lol. Thanks

Not sure what brand brake controller you are using, but this may help.

im confused? what do you need?

hes needing the brake light signal for the brake controller. it uses the brake light signal to determine when to apply the trailer brakes.
look for the brake light switch on the brake pedal and tap into that wire. while your down there make sure its adjusted right so that it turns the lights and signals the controller at the proper time. as in turning the brake lights on before the brakes start grabbing.

x2 got it, yeah switch is up on the brake pedal, tap into the dead side wire on the switch...hot only when brake is depressed...use a test light to figure out which wire..

Ok, gotcha. I thought I already used that light switch under the dash but I didn't check it with a test light. I'll check it this time with a test light to make sure it turns on when pedal is pressed and that its adjusted right. Thanks.

Should be a white wire, the orange wire is hot all of the time.
