Question

[1978Blazerk5]

Hey i have a 78 blazer, my question is i have a wire hanging there i am pretty sure its for a trailer brake if so i need a controler right. whats a good affordable controler
Thanks


heres a picture of the wire
edit i am sorry there is already a thread on trailer brakes

Where's the other end? Looks like a primary wire. Look to see if it goes to the break light switch.

i will tell ya right now i don't know much about this stuff
according to the previous owner the truck had a trailer brake on it

Then it should be the Brake signal wire for the controller. Also known as the blue wire. put a volt meter on it and step on the brakes, with the ignition on. If you have voltage that's it.

You gotta follow the wire. It could be the supply wire for the controller, the wire that goes to the trailer, or the wire that comes from the pedal (control). But it looks like to big of a wire for the control.

where do i go to get a controller

 

[skyyk5]

Most auto parts stores have cheap ones. I got a good one from a Heavy truck center.

well i tested it today with a test light and it always has power what does that mean

 

[skyyk5]

It's the supply power that comes from the batt. and goes to the controller

allrite so besides a controler is there anything else i will need?
Like i said in a earlier post i dont know much about this stuff

 

[skyyk5]

The instructions with the controller will tell you more. My tow rig is a 03 sierra, so all i had to do was plug it in. You have to see if the wire from the controller to the trailer conector is still there / in good shape. and the wire from the brake pedal. Other than that It's simple.
