trailer aux power

[Linelife99]

I have a 2006 yukon xl denali. At the factory plug for trailer there is no power at the positive blade. On 07 trucks there is a wire to hook up, is there something similar on my yukon? Thanks.

Fuse Block under the hood......I believe it was STUD 1, and was a 40 amp fuse. If you go thru the owners manual, it should show it there. I went years towing my camper not knowing this fuse needed to be installed, and wondered why the truck wasn't charging the camper battery........make it even more embarrassing, the fuse was in the glove box the whole time....had to be 4 years

Thanks. The fuse was blown.
