Okay the image is showing.. that's your PDC is it?

 

Yeah that's under the hood.

 

dodgeramguy85: It's quite different looking than mine, either way I don't have any 40A fuses marked "trailer" in the PDC.

Regardless, it works. Trailer brakes work, so I guess I did it right. Still don't know where these fuses and this relay are that are supposed to be under the hood, but if everythings working, I guess I don't HAVE to know.

Note that on Reese trailer brake controllers, they list their white as ground. On the Dodge pigtail it's black, so you have to cross wire black and white from controller to vehicle.
