Dorman is a company that manufactures the replacement 4wd actuator (mecanical type in lieu of thermal) in the front differential. They also manufacture the corresponding wiring harness. I contacted Dorman and they were kind enough to email me a completes set of electrical drawings/installation procedure.

 

Thanks,
