I have an 2000 Durango, SLT 5.9 with trailer tow pkg. I upgraded to a larger popup camper that requires trailer brakes, so I bought a brake controller today. My Durango came with a 4-wire harness to plug into a connector under the driver side dash, and I spliced the 4 wires from the controller and connected to the harness (both had red, lt blue, white and black wires so I thought it would be pretty basic-plug and go). The controller seems to have no power or do anything, so I hooked up the trailer, thinking it would only work with the connection to the trailer made. I pump the brakes, nothing! Any ideas on what I am doing wrong or where to start??

Thanks!

 

IIRC,

Blue, trailer breaks

Oldschool, thanks for the info. Are you suggesting I skip the harness and wire the controller myself?

Thanks

 

You could but, it you bought the harness that already has connectors on both ends it should work... Did you try looking in the PDC and see if the trailer tow fuse is blown/or there? should be fuse #6 40A.

 

Thanks, I got out the multimeter tonight and figured it out. Not sure if all 2000 Durango's are the same, but the factory harness wiring was opposite of what I thought. Black was ground, red was 12V power, white with brown stripe was brake sensor and blue was trailer brake. Once I matched that up to the brake controller (and replaced the brake light fuse I blew the 1st time!) the brake control worked perfectly!

Appreciate the help!

 

no offense meant here, but the black as ground and red as the 12v feed is pretty standard across all electrical wiring iv ever worked with so im hoping those two arent the ones you got mixed up.

 

Brake controllers are different......
