I'm in process of converting my 1988 MJ to run on a 2004 GM computer and wiring harness. I used all of the GM sensors except the CMP, TPS and IAC. The crank reluctor I made in my home shop. It's a 3x just like the factory V6 is. I'm using the Jeep Cam trigger and just wired it into the GM harness. This is the first start up so the wires are just laid on the engine. I have wire loom coming in to wrap it all in.
I'll be posting more info and pics as I get it organized.

So I got the O2 sensor hooked up today and on the short test run I made it really helped it. I'll be driving it about 60 miles tomorrow, so we'll see how it does.
I'm running one O2 with it hooked to the input to both bank 1 sensor 1 and bank 2 sensor 1. I'm using bank 1 sensor 1 12v to heat it. I turned the DTC off for the other O2.
I've also got the fans running off the computer.
