2005 dodge 2500 diesel it has a new brake controller. trailer brakes work when you push the controller manualy but trailer brakes don't work when you push the brake pedal


there is likely a wire that goes from your brake pedal switch to the trailer brake controller this wire is probably broken or not hooked up. if it is hooked up and no wires are broken I would start making sure everything is hooked up right.

How do you find out if you have the wires for a tow package? Trying to hook up a trailer with electrical brakes.


The wires would be secured under the rear of the truck. However trailer wiring is only for trailer lighting. Electric trailer brakes require a trailer brake controller.

We just hooked up our Ford 1996 econoline van to a trailer. The trailer brakes are not working. We checked all the fuses - all seem to be fine. The fuse diagram on the fuse box panel does not tell you...


First thing is your van equipped with a trailer brake controller and is it working. This is usually a small box that is installed inside the vehicle and is needed to operate the brakes. Next what type of plug do you have on the vehicle to plug the trailer into some plugs do not support wiring for trailer brakes. If you have a aftermarket trailer brake controller it will not be fused in the fuse panel so you will to locate a inline fuse used to power up the controller. Hope this helps.

When I hook up to a trailer, the left turn signal and the left brake light won't work. I have tried several trailers with the same results. I own a 2003 gmc 3/4 ton pickup. I have two places to connect the...


it sounds like either the wires controling the left brake light and turn signal are borken or loose on your truck. or there could be a problem with the ground for the trailer hookup. you should take a volt meter and then have someone put the brake on and test at the hook on the truck side to see if you are getting any voltage there and do the same thing with the turn signal. if you do not have any voltage there you need to trace the wires back up into the truck to find where you do have voltage . you may find a broken wire as you go. How many wires are there in your trailer hook up?

All lights work and brake light at top works. brake lights on bottom left and right don't work. It was hook up to trailer wires connection. going down the road and when you turn on the right turn signal...


Check a few things...
- The bulbs
- Check for ground at brake lamp connectors
- Check your wiring at the connectors for power
- Check for another fuse blown
- Do not hook up the trailer until you fix the ground problem on the trailer
- On some models, there is a module to control the rear/trailer lighting system. There may be a problem in the module.

Trying to connect a teekonsha voyager brake control to a 2003 expedition


Their should be a 6 pin conector that only 4 pins are used somtimes a 5th wire is installed for illumination, don't worrie about using that one. The connector is located in one or two different spots, the most popular place is under the dash on the drivers side just below the steering column the connector is grey. The colors are black or red / blue / green / white and sometimes a small black or brown wire is for illumination, don't worrie about that wire. Their are wiring harnasses for sell to hook the brake control through the conector, but if you do not want to buy an adapter hook the wires as followed: Vehicle Brake Control
Black or Red Black
Blue Blue
Green Red
White White
Black is power in to the brake control
Blue is the trailer brake feed
Green is brake signal
White is Ground for the brake control
