Which rear harnesses do I need? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

In my cab I have a 4-pin connector, lt grn, dk grn, brn and yellow if I recall. Two pins up and two sideways. I believe this is the rear body connector.

My old one was all cut up for trailing wiring, camper wiring, and who knows what else they added.

I've found the rear harness (MH 22075) but there's also listed an "intermediate" rear harness and I'm not sure what that is.

Does anyone know what all I need to wire from the under-dash connector all the way back to, and including, the tail lights?

Thanks!
Dave

There is the main harness that runs from the round connector on the firewall to the rear cross member (I would call this the intermediate harness) and the rear harness from the connector at the rear cross member to the individual rear lights. The only other thing you would need is the license plate light.
