Engine wiring harness routing on a 1994 Explorer.

Anyone have photos of the 4.0 1994 explorer engine wiring harness routing and connector locations as you rebuild the engine? Like photos of the wiring with the lower intake manifold on, then the upper half on, etc.

Welcome to this forum! I've moved your thread into the stock 91-94 section.

if your looking at hooking a motor that was pulled back up honestly the best thing to do is start at one end of the harness and just go from there. each wire is only so long, swing it in an arc from where it branches off and your bound to find its mate. most of the harness will kinda fall into place as you go along. its time consuming but it works

Thanks. I got it! I had to take the intake manifold top off again to route the wires. The one I was missing turned out to connect below the water pump (the tach I think). I had it way over by the steering column. In doing so, I was able to find about 10 other things that were worth checking and tightening so I am about ready to fire it up after the head job. I have a leaking power steering unit - I picked up a pump at the junk yard but now I think the actual steering box is the culprit. That can't be easy to change. It started leaking a few months ago when I tightened the screw on the top (with the lock nut around it) to take us some slop in the steering - something I used to do on cars back in the 60s and 70s when they had excessive play. Could that have caused an internal leak? Anyway, I also stopped a few people in town who also have a 94 and found out where each of the vac lines come from and go to at the right rear of the engine. It should work fine - I'll let you know. Jim
