03 yukon trailer wiring 12v

[Krambone]

I have an 03 yukon xl with the factory towing pkg. On the 7 pin connector the 12v piv has no power. Prior to this I had a Ford Expedition & Ford leaves out the relay for the 12v pin. Is this a similar situation? I've gone through my owners manual but it is not very clear. I'd greatly appreciate any help.

I think there is a large maxi fuse in the engine compartment fuse panel.
