In your fuse box under the hood... there are 2 fuses marked pole 1 and pole 2. One of these is the fuse to feed 12 volts to the trailer. The poles are located under a smaller cover just behind the main fuse box under the hood. The wiring may have to be connected to the bolt/post.

Hi, this may true if you connected the trailer brake to the connector on the factory wiring harness. There are several fuses that are needed for trailer towing. In the box by the battery, fuses 13, 25, 27, 53, and 54 are needed. You will need a relay in relay slot 19 for the trailer running lights, a relay in relay slot 20 to charge the trailer emergency battery; and, if your trailer has backup lights (6 or 7 wire connector), you will also need a relay in the relay slot 15. If you did not use the factory connector for your trailer brake controller, check to make sure you have connected the controller to an appropriate power source in the truck. Please let me know if you have questions, and thanks for using FixYa.

Have no power out of the trailer plug 4or 7 prong,where should i look for the trouble?


Not sure which part you mean no power.

For the New Body style 2004 ( not a Heritage or Lightning model )

If both Stop / Turn pins & the parking lamps, might want to check the ground pin to make sure it is good ( or what you are using for ground on the test light / meter ).

The trailer tow parking lamp circuit is fuse #10 to the parking lamp relay

The stop / turn circuits also have fuses on each one, Fuse #36 & Fuse # 42 ( R & L ).

The 7 pin has fuses for the battery charge pin ( hot in run position ) and the reverse circuit ( hot in run & when in reverse ), Reverse is also fuse # 10 to the trailer tow reversing lamp relay & the battery charge pin is fuse # 106 to the trailer tow battery charge relay.

Could be all the fuses are blown, or what you are using for ground on the meter / test light is not a good ground.

The fuses for the trailer tow adapter are in the normal fuse panels.

Engine Compartment fuse panel
101 - Is the battery charge circuit ( hot in run position )
20 - Left Stop / Turn fuse
19 - Right Stop / Turn
5 - Trailer tow reversing lamps & Trailer Tow parking lamps

Cab Fuse Panel
23 - fuse for the relay for the trailer tow battery charge circuit

All of these are in the owners manual

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

Trailer harness - Red wire has no power


Hi: under the hood in the power distribution box there is a 40 Amp fuse that has to be installed to power up the trailer package. When standing looking from the front left fender it should be at the front right corner, refer to the power distribution diagram on the cover. As well under the box by the spare tire is a plug in type module mounted on the frame. There should be 2 wire harnesses located there, make sure the correct plug in is connected. Hope this helps... please rate suggestion .... ty

2003 duramax 2500hd brake lights stay on when lights are on


You may have faulty wiring for your trailer lights. Look under the back of the truck where the wiring harness leads to the trailer wiring harness. Usualy it is a 3 way plug in the harness. Try unpluging the harness from the trailer wiring and just plug the other 2 wires into eachother
Hope this works for you!
