24X harness repin? I am looking to have my harness repined to run the 24x ignition, but I can not find anyone how offers this. Is there anyone out there that will repin your stock harness to work with a 24x ls1 pcm? I emailed www.pro-jectioneng.com, but they have not responded yet.

I did it, it's not that hard. You can do it with the engine in the car. I did mine out since the engine is out, but you can do it. it will take a solid day. here's my writeup progress. i'll get more pics when i get it close to getting back in the car

it's really easy to take them out and yes that is the gist of what you are doing. Moving pin from harness A over to harness B in a different hole.
You use the pin tool that comes with the 24x kit. You can even remove them by hand, they are easy to take out, you just have to look at the mechanism. I did not do soldering, just took out extra wires that I didn't use (traction control, air pump, etc), but you can just as easily leave all that in there. think of it like wiring a car stereo that has 4 outputs for speakers and you only end up using two. You don't have to cut/remove the other 2.

I am going to start and hopefully finish this week end. The only questions I have is I did find these for the ls1 pcm http://www.eficonnection.com/coilper...s_LS1_Blue.jpg
http://www.eficonnection.com/coilper...ns_LS1_Red.jpg
but what about the lt1 pcm harness?
I see the lt1 pinouts are on the right and the ls1 pinouts are on the left.

follow the guide as mike says. The red/blue are exactly as you need them for the LT1. I made the same mistake, but just a little more reading and prep. I also downloaded the schematics for the 2000 ls1 engine and i have the factory manuals.
the trick is to really think one circuit at a time one wire at a time. and keep track of what you are doing.

^ Thanks, but I just printed out all of the info for the pcm connectors on the lt1 now I am going to look up the info for a 2000 z28. This job is starting to look simple; I am sure I can have it done in one day, just depends on how dificult it is to remove the pins from the old harness and install them into the new ls1 connectors.
