GM techs
I have a 2003 Chevy 2500 HD, with the towing package. I have never used the 12 volt feed on the 7 pin trailer plug. Old trailer did not have wire on the trailer plug, and honestly never checked the truck for voltage on the pin.
My new trailer uses the truck for electric jack and 12 lights in trailer. I do not have 12 volts on the red wire on the truck side. Tried looking at manual, and it is worthless. Do I need to put a fuse in, or what do I need to do to get the 12 volt feed thru this harness? thanks Ken |

Re: GM techs
In the underhood fuse box there is a place for a 40 amp j-fuse , it is labled stud 1. There should be a red plastic thing stuck in that position. Pull out the plastic and install a 40 amp fuse and you should have 12 volts on the red wire.

Re: GM techs
Ken,
Fuse should be on the top left of the fuse box under the hood. As Jerry said, it comes with a red dummy fuse in it. You have to remove that, put a fuse in, and you should be good to go.
