Does the rear wiring harness unplug?

[custom10nut]

In the near future, I’m going to be unbolting, and lifting the bed off my truck.
I’m doing this so that I can paint the back of the cab and front of the box.
My question is:
Is there a way to unplug the rear portion of the wiring harness, or another way to disconnect it without cutting the wires? I really don’t want to cut the wires, only to have to splice them back together.
I hope the Factory Surely made a provision for disconnecting them.
