01' Ram Trailer Tow Relay Where Is It?

I had no luck finding it and had the AC repaired at the dealer and they had no idea. I couldn't find it on the net and neither could they. I have been on the truck form in the past and got no answer. This is for the hot black wire (that circuit is in the seven pin connector at the hitch) to the trailer batteries that charges them when the truck runs.

Thanks

That's the wiring diagram says the relay is the power distribution center, which I know it's next to or a part of the fuse block. So far I see nothing there that comes close to my after market relay, that is if the after market one is correct. Many thanks for the link. I'll give it another look. This was brought about from to short of wire harness from the trailer to my truck. The trailer is new to me and the harness to short for a tight left turn. That was the start of my problem. Two blown fuse and a new seven pin connector and now no power to that circuit.
