So, I just connected both wires to the two separate threaded studs and retained in place with some electrical tape. The tape lasted for a few days and a few hundred miles until I came across a hardware/auto parts store. (NO nuts on the posts.)

However, that's a nice photo.

I should have checked before leaving on the trip, but I didn't and believed the dealer's tech when he said he had connected the power feed wire to the fuse block. When I purchase my next Silverado in a few months, I guarantee I will make sure there is B+ power to the 7-pin connector.
If you buy a new truck with hd tow package there should be a service note in with your owners manual for the charge wire.

I did get the HD trailer package, and there was no note in the owner's manual. But the vehicle was purchased new, locally at a Moab dealer, but it was originally shipped to a Grand Junction dealer. So who knows what happened between the two dealers.

All I know is the wires were not connected by the tech and when I got back into town, I went into the dealer and asked Mike the tech, exactly what wires he connected. He was slightly embarrassed, gave me a free oil change (I supplied the oil, he did the labor) and assured me, the next truck WILL have the wires connected.

For a small town dealer, they actually have a pretty good service department and Mike, is a pretty darn good tech.

So, time to move onto another thread....

It's not that somebody forgot to put the relay in it's just that Ford includes the fuse and relay and put it into a plastic bag and it's usually in each truck. They don's install it. There's something about not wanting the hot wire going down through the truck unless you are going to tow. We bought a 2010 F-150 and they knew we were also going to buy and tow a TT and they did not install or even tell us that we needed to do the same to charge the trailer batteries. After a friend of mine did the same thing the camper dealer told him about the fuse and relay. He found it in the side door compartment.

Thanks for all the replies. I cleaned the terminals after reading the first post with no luck. I just got to read the other posts tonight (after driving all day with batteries not being charged). I have a 2005 suburban that was probably never used for towing, so I'll search out the spot for the fuse tomorrow and see if that works.

If the tow charge wire was never energized via a fuse or relay it still isn't.

Nice diagram Turbs but, if your sitting on the ground with a test light or volt meter probing under your flip up weather cover, refer to the 7-way Trailer side diagram. The diagrams depict the "back side" of the respective connectors where the respective wires would be attached.

So, the "pin" near the "1 o'clock" position should be "hot" with the ignition in the "on" position.

I had a 2002 Chevy and if I remember correctly, flip over the cover of the under hood electrical center, and the location and purpose of each fuse/relay is indicated. In my case I believe it was labeled AUX 1 and AUX 2 and they were 30a MAXI fuses. In later years, not sure exactly which year, they went back to the regular type mini fuse.

But anyway, with all of our fellow campers' input you should be able to figure it out from here.

This is not completely correct for Ford. They use a relay AND fuse. Just went through this issue yesterday. For my truck the relay is in socket #9 and the fuse in socket #21 in the fuse panel under the hood.
