Doing an ls swap in an 02 blazer xtreme. I've got the stand alone in and just about wired up. What I'm having an issue with is the original vehicle wiring now, when I hook up power I originally got nothing but I found a ground in the original harness and now I get the fuel pump prime and just about everything else working. But it's acting really weird, almost like the BCM isn't getting full power or there's another ground I'm missing. I am running dual processors, 1 for the stand alone and 1 for the vehicle itself.
Anyway I'm tired of fucking with it, I've spent 3 days and 2 trips to the junkyard and got nowhere.
Anyone know their shit when it comes to wiring? I'll gladly pay for your services. I'm located in Dearborn
