H2 trailer battery fuse?

[jrs2005]

2005 H2 - I don't have power to the interior lights and winch in my car trailer. Brake lights, signals, and electric brakes work fine. The owners book says I need to add a trailer battery feed fuse, what is are where does this go? When I plug the trailer into my 2002 tahoe everything works fine so I know its the H2 that has an issue. Thanks in advance...

I believe the 2003-2007 trucks just need the fuse plugged into the box/panel under the hood (located under the hood on the drivers side right above the wheel well)...... its been a while but I believe that is all I did on my 2006. Your owners manual should have a fuse diagram in it with descriptions for each.

On my 2008 I had to find the wire in the loom, hook it up and add the fuse, wiring in the brake control is also not a plug and play harness on the 2008.

If for some reason you dont have your manual..... I have a 2005 Owner's manual on a PDF, its too large to attach here but if you shoot me an email at m.kennedy75@comcast.net I would be happy to send it to you.

I had a similar problem, try and clean the contacts in Hitch Receptacle in the Bumper and the plug.

Well its under the hood top left corner of the main fuse panel. Had a red blank in the holder labeled B+. Pulled that out verified the red wire back to the 7way harness. Put in a 40 amp fuse and now all is well. Really be nice if the owners manual or the helms manual had this info in it.
