Progress on the LSX Harness Conversion
Progress on the LSX Harness Conversion Took my Harness today to one of the guys in the local area who tunes. What I had did was take a LS1 Harness, and make it a direct plug-in into a 1995 LT1 Car. Then I got ahold of a 2002 LS1 PCM out of a TA to use. Hooked it all up, turned the Key on, and blew the PCM Ignition Fuze instantly. We were, however, able to pull the Tune out of the Computer. That means progress, goal achieved.
As far as the Fuze, it is the PCM Ignition circuit. What I think caused it is that the grounds for all that stuff in the Harness were not grounded cause they bolt to the back of the Drivers side Head on the LS motor., and no Tranny was connected up.
Hey Rhino, if you read this, I think it is that. I know I mentioned it up there. If it isn't, it's one thing out from narrowing it down, but I think it is. The one ground on the Chassis was for the PCM itself, but all the major stuff(Ignition, Injectors, Trans, etc..) was not grounded.
The hard part is done, just a little bit of trouble shooting now. All I need is the Motor...

more info on harness I second that, how does the stock 95 lt-1 harness get attached to the ls-1 harness? I would think you needed to remove the lt-1 harness that attaches to the motor and keep the stuff going inside the car?
