No 12 volt charge power at 7 way plug.

I've got a 2018 Ford F-350. So I decided to cut the Lance propriety plug off the camper and wire up a bargeman. I had a cord I bought from Torqelift many years ago, just in case I bought a new camper. The Torqelift cord was wired incorrectly, which is another story. All the lights work correctly but I have no power to the 12 volt charge line, Running or stopped. Looked at the fuse box and in the #27 slot there is a 30A fuse so I'm thinking I'll go talk to the Ford dealer tomorrow unless someone already knows the answer.

Does the F350 have the camper package which includes the relay installed for that plug to have the 12v working?

My 2017 F-350 requires the camper to be plugged in, so it senses the load, then with the truck running press the brake pedal for >3 seconds to activate the power circuit. If I remote-start the truck, I don't get power back there until the key is in and on.

It's common for the factory to leave the fuse out.

If the fuse diagram says slot 27 is where the fuse goes for the 7 pin plug, put a fuse in. That's what I'd do instead of going to the dealer and have them give me a "deer in the headlights" look when I ask them about it.

On earlier GM trucks, the wire wasn't even hooked up to the power stud.

Also a large relay in slot #37 (Trailer tow battery charge relay (only on non-trailer brake controller vehicles).)
