Install EFI connection LSX PCM
Check out their website - probably a way to contact them to ask them these questions.

Anyone know what Pin number it is on the harness? BTW I ditched the DIY harness and have one from EFI connections.
However I can just run a wire from the PCM at Blue 55 (02 411 pcm) and enable the EGR to gain volt reading for my wideband.
Found my answer https://ls1tech.com/forums/pcm-diagn...d-vehicle.html
Im running a gen 7 dfi and was using dual sync for inputs Im looking to put on a crank trigger setup for crank but would love to have a cam signal right off the cam too if it's 1x.
We just finished a DIY EFI connection 24x swap on a 95 Z28 manual trans, 383, AFR 227 heads and a mid 230's/mid 240's duration etc.
The car made awesome power (448 RWHP 421 RWTQ SAE dynojet 224xlc), drove great, and everything went really smooth. I'd say the harness work took us about 4-5 hours but it was all pretty straight forward and easy. We custom made the plug wires and welded little bosses for his coil packs to bolt on and off the valve covers.
It really doesn't make sense not to do this swap. He was able to sell his MSD optispark, 95 PCM, coil, plug wires (almost new), MSD box, etc and come out not making money but spending about as much as the next optispark swap he would inevitably had to do otherwise. Your replacing wearable parts with non-wearable parts.
We are trying to talk everyone who has a LT1 that has work done at our shop to do this, especially if we have the engine out for any reason.
