I am trying to hook up trailer brakes on my blazer I have a controller but do not have the plug, I was looking under my kick panel down by the brake pedal today and found a 4 wire plug, I am wondering how about go hooking this up I have a 7 plug hooked up in the rear currently all the lights work now I am trying to do the trailer brake. I was trying to find a module also thanks..

 

I just finished this same job yesterday. In my 2000 Jimmy, there was no vehicle plug to connect the brake controller to. My car had the trailer package but not the HD trailer package(which I believe adds the brake controller wiring).


What "module"?

 

Ok I have only 4 wires on the back of my 98 CHevy blazer LS..so I am stuck at this point

 

Ok so i went and looked at my rear wire trailer wiring again and I found that I have 6 wires. can anyone tell me what the other two go to??

 

Here is my trailer brake controller, I know the end is wrong of course this is a ford connector, I am trying to locate the correct plug?

 

rear of truck colors are:


Brown = Running lights
Yellow = Left Turn/Brake
Dark Green = Right turn/Brake
White = Ground


Light Green = Backup lights
Light Blue = Aux Stop light




Wires coming out of the controller, where the splices are, may be:


White = Ground
Black = +12V input (20Amps)
Red = Stop light switch (White wire at switch terminal A)
Blue = to trailer brakes


I don't think there is a "connector" to plug the controller into in a 2nd gen Blazer. I may be wrong on that. Definitely not on my car. Even if you had the HD trailer harness with the HEAVY Blue wire, there was no "connector" up under the dash. I think.....


If this is correct, you will have to run a heavy wire from the battery, to a circuit breaker, to the controller and then back to the trailer socket.

 

Where is the Red = Stop light switch (White wire at switch terminal A) located?? I ran a wire from the front all the way to the back to hookup the trailer brake wire to the plug. I just cant find the Stop light switch wire (White wire at switch terminal A) Can you please tell me where to look thank you

 

I found it posting a pic and some useful information where i found it...

That'll work. I tapped into the line at the brake pedal switch. Same thing.
