I worked on the wiring all afternoon. The F-body wiring harness is designed to put the PCM in the pass side.I need to mount mine on the drivers side on top of the battery. My plan is to take the harness apart sensor by sensor following the wires to the PCM then labeling the pin location. All the wires on the drivers side are going to be proximately 10 inches too long. Those will be cut down and new terminals will be crimped on then they will be reconnected. The passengers side I will disconnect reroute and reconnect they should be perfect. In the processes of dis-assembly I will omit any sensor or wire I will not need. I will also hunt down the 12V commons.
The grounds I will be leaving alone so far they will ground in their original locations on the block.

Looks good in there. I just ordered a High mount braked for a sanden type A/C compressor. What did you do a bout the lines? How did your A/C work? Is it stand alone or wired into the LS1 PCM.

All joking aside it may seem hard but if you take your time and do your homework it's just another job.

my ac is still unfinished, but i made all the accessories mounts and such to mount the stock compressor in a stock location, but now the lines are short by about two inches, as far as the wiring, its just uses the stock wiring, and the lsx pcm only requires a signal wire to bump up the idle as it will die when the compressor kicks on at stop lights and such. but again, i cannot verify if mine works yet.

I could have avoided all this if i just found a place to put the PCM on the other side.

Well, if you man up and get rid of the HVAC system...Just kidding, I wouldn't get rid of it either. Especially living where you live.

I would have to get a custom plate that said "GTBKLSRG"
I think that's one too many letters.
