83 Crew Cab Rear Wiring Harness?

[EricU]

I have the bed off my 83 C30 Crew Cab while doing a C-notch and rear flip kit.

While I have it apart, does anyone make a rear electrical harness assembly that plugs into the main harness at the main bulkhead disconnect and covers all the little things at the rear of the truck?

Looking for the taillights, backup lights etc – fuel tank sender’s wiring would also be nice to replace.

And hopefully not with a 12-week lead time!! – I know, I know, the world has fallen apart due to Covid….

Thanks for any help! (and yes I did a search)
