Camper Special wiring harness

[Nomadicflyer]

I'm installing an AAW Classic Upgrade kit, but it doesn't include the heavy duty wiring for the camper plug or trailer wiring on my 72 C20. Before I go making up a new one from scratch, and figuring out where to splice it into the new harness, I thought I'd ask for help.

Anyone been there/done that? Does anyone make such a thing? What kind of plug did you use for the camper outlet at the cab corner?

Secondary question: If I'm going to add an isolated trailer light package, I'm thinking I should power the camper off of that circuit, and add on a power lead for camper accessories. That way the camper will be isolated, any shorts won't affect the truck, just the trailer circuit.

Thoughts? Suggestions? Thanks!
