I just got my 2008 GMC 2500 HD truck back from the dealership with the same problem. They informed me that the accessory power is no longer hooked up by the factory, that is now the responsibility of the owner of the vehicle. The service tech showed me where the wire was and I connected it to a Stud 1 outside of the fuse box. You will also need a 40 amp fuse for position 68 on the fuse block.

Trailer wiring


Trailer wiring uses the fuses for the car lights. Turn signal, running ans brake lights. Some plugs also charge the trailer battery if so wired. Check the ground wire for a good body connection. This wire often gets overlooked and can stop all trailer lights if it fails.

No power to trailer plug on toyota fj fuses are good


if you mean a 4 pronged plug at the rear of your vehicle that allows you to plug in and tow a trailer safely and legally , then get yourself a testlight and check each prong for power. 1 leftturn, 2-rightturn, 3-parking lights 4-ground .if you have no power at plug check condition of wiring connections at plug and follow harness to source. if you have power at plug the problem is in the trailer. check groundwire, wiring,and bulbs.

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.

Can't get the trailer running lights to work on my 2006 F350 Diesel 4X4. Tried the trailer on another vehicle with the same plug and they worked perfectly. All other lights work with the trailer when the...


Check fuse 28 in the fuse block under the left side of the dash. There is also a relay for the trailer park lamps in that same fuse block. The fuse and relay are the trailer parking lamps and run independantly of the vehicles parking lights. You can also try backprobing the other trailer plug (you should have one 7 pin and one 4 pin) to see if there is power at the park light pin. If there is power at the other trailer plug than the fuse and relay are bad and you may have a bad/corroded plug or bad wring to the plug that doesn't work.

Running trailer lights not working, but brake


Did you check the fuse for the trailer tow adapter paring lamps ? This is a separate fuse powered by a relay, it is not the same circuit as the truck's parking lamps.
This is fuse # F10 & The half size ISO relay, R201 in the fuse panel in the passenger side kick panel.
This is based upon being a new body style 2004, not the 2004 Heritage or Lightning models, those are different fuse & relay locations.

No power to rear plug for lights on a trailer fuses look good


Do you mean nothing works or just the power lead? If nothing works I would check the ground. If just the power lead doesn't work on the I know on the older superdutys the large fuses had to be installed in the fuse box under the hood to make it work. They were usually in the bag with the trailer brake controller wiring and had directions on where they went. Hope it helps

I lost the light in the 2003 Duramax a few week ago.I just found a blown fuse under the hood in that big fuse panel by the driver side. It was the 15 amp mini fuse on the upper left hand corner. There was a white arrow pointing to it. Evidently someone has had the problem before. I bet that's my culprit
