Ok.. now for you guys to put your thinkin’ beanies on & give a fellow brother some help….
I have located the 2 obdii wires for the obd connector (circuit 2500 & 2501) tan\blk & solid tan. The connector I bought (recommended) is the ICT connector (4 wires-ppl,orng,2 blk) I believe the purple wire is my “data”, the 2 blk are grounds (signal & chassis) and the orng is constant power. I am not sure what to do with the 2 “data” wires from the ECM in relation to the purple wire?
1) Do I need to get a factory connector from a donor? (what years would work)
2) Can the orng wire connect to the fuse block?

I have posted this in the electrical section to try to get a little traction on this..

thanks!!!
