Wiring harness Q's
I have a 94 ranger, came with a 4.0 V6 when I bought it. I believe the engine was swapped into it and the engine was from a 93 since it doesn't have EGR. I could be wrong I'm kind of new to Rangers. When I got the Ranger the engine was blown and I was well aware of that, so I bought another used 4.0 complete engine. As I was cleaning the new engine I started noticing the EGR and the accesory brackets were a bit different. At this point the new engine looks brand new. I cleaned it all up, prepped it, and painted everything silver and black with 2000 degree paint. I decided to use the wiring harness that came with the truck as it looked to be in better shape. Problem is the old harness doesn't have the EGR connection or one big connector that hooks up to the engine bay (near the fusebox). On the new harness there are 3 of those big connectors. Also the new engine has what looks like a small module with a connector on the rear of the engine, and the old one has a blocking plate there. I think it's for timing, I'm not really sure. My main question is, should I cut open the new harness and figure out what I need and transfer it? Or should I just clean up the old harness and transfer whatever is broken? I'll post up some pics tonight to kind of clarify my questions. Oh I also forgot to ask, what is the difference between the red and blue top injectors?
