LS wiring harness combining wilth old 72 Jimmy
 

I am putting a 99 Silverado 5.3 and tranny into my Jimmy, I have the wiring harness and the pcm from the donor, but I will have to replace all the original wiring from the Jimmy looking for information on vendor or person that does the retrofit.

he will build you a stand alone, or take yours and take everything out you do not need. I have gotten a couple from him, let him know that I sent you if you decide.
