camper special wiring

I pulled the front tank from my 78. I found A pigtail with a plug in the end of it. It looked like a flat 6 or 7 prong plug. I am wondering if this is part of the camper special option. What does it do?

Thanks, Todd

Yep. It's the feed for the camper body.

Post a pic just to be sure.

I am not good enough to post a pic. I finally got around to testing the plug. It is a flat 6 prong plug with a factory plug in it to keep critters out. If you remove the cap you can see 1 male prong and 5 female prongs. starting with the male prong the wires tested out Ground, Right Turn, Left Turn, Taillights, B+, ???.

Does any one have any idea what the last wire is used for. I could not get it to show any voltage with my test light? Also, does any one have any idea if the other end of this plug is available? Lastly, why did they bury this handy gadget in such a inaccessible spot? Must be so every PO prior to me could attempt their own trailer wiring?

This connector is there so you could plug into the harness that came with the overhead camper, and have all your lights work correctly. Back in the day you could probably buy the other end of this connector at the parts counter, but I'm sure its long gone by now.

This last pin should be for the backup lights, check it out with your test light.

ok so i see in the parts book that there was a trailer wiring kit. Does anybody know how the trailer wiring kit would have worked - i'm not sure I've seen any trailer electrical connections on these old trucks mounted at the rear like what comes on the newer trucks today. Any thoughts on this since it goes along the lines of the 6-7 pin connection that was found up under the truck that was supposedly for the campers?
