The truck lights and Camper lights (camper circuits tap into The Truck circuits at the front of the camper) seem to work fine.
There (8) separate wires-in the truck lighting harness designed for a 7 wire trailer plug. I have not been able to get these wires life.

I just Replaced this relay-with no change--in any of the simple circuits (Lf, Rt turn, running lites,back up, 12v hot, ect circuits. Open for a good direction in finding the missing relay, tkx phil

I am sorry I am confused, You have a bundle of wires, have you tried to tap into any of them? you said no power on any of the wires. I just need to know what the wire colors are on the truck side only, and what ones work with power and what ones do not, I am sorry in that I am not following what you mean by front of bed, camper, trailer circuit etc

Randall--as noted, there are 12 wires in the bundle--4 of them supply turn, stop, runnng lites, and back up at the back left side of the truck. The camper tied into these wires for its markers, turn, back-up and stop lites. Also at the back, left side of the truck are the other 8 wires, in 2-4 wire connectors. at the wrecking yard, I found a 91 ford with a wiring harness that plugged into these 2 connectors to feed a 7 wire -standard Trailer plug. I believe there must be a Relay that is currently keeping these wires dead. Under the hood, on the right hand side, there are several Relays. One of them is marked Trailer Towing Package. Today, I put in a new Relay--but still no power. Hope this helps. I would be glad to discuss on the phone, but am hesitant to pay an additional $26 on top of the $36 already paid. hope this helps phil ***-***-****

Randall--I appreciate you trying to help--and refering me on. This is a challenge--I have reached out to several sources--with limited success. As I mentioned, there is a Trailer Towering wiring Relay-which I replaced--but I have not been able to identify what activates this relay-so the trailer wiring becomes live. phil

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
