hi everyone, this is my first post on here. i have a 95 xl that had a tired/knocking 300 with 300k. i decided to put a 302 ho out of 99 explorer in her. i have the WAY1 ecm. the engine harness is from 5.0 maf truck. also recently noticed i needed the harness that goes from ecm to fuse block etc because the 4.9 version didnt contain the extra 2 feul injector pins. so i grabbed that and put it in. having some issues with things like ac unit (by firewall) needs 2 wires and the 5.0 harness has only 1. i need a detailed diagram of all harness' and a pinout diagram of the way1 ecm. cant find what im looking for online and was wondering if anyone on here might have what im looking for
This forum is mostly guys just trying to keep their old trucks running well. Your question is pretty specialized. You'll probably get the diagrams on an explorer forum. There's also this website:
