Brake controller wiring????

My 2003 ram 2500 only has the 4 flat trailer wiring and my enclosed trailer has 7 pin. So I buy a controller with factory plug in for under dash which my truck has BUT on my adaptor at the bumper (4 to 7) I have three wires coming out blue/brakes, black ?, white ground lug... Where do I need to run these wires so the controller runs the brakes???? Not wanting to pay $70 hour for someone to install two wires!!!

Re: Brake controller wiring????

do not hold me to it but blue goes to brake control, white ground, black may be 12v. etrailer.com should have a diagram to help you out.

Re: Brake controller wiring????

Here's the problem though... My controller has the factory plug under the dash and is already plugged in but no blue wire to the rear of the truck...
