I have a pretty straightforward question. Truck is a 97 explorer sport 4.0 ohv with control trac and manual tranny. I decided to replace the engine in it so I got one with 50k on it and want to drop it in. Only problem is that engine was from an automatic transmission vehicle (no surprise there, seriously how many stick explorers are there?? lol) and the wiring harness is slightly different. There is an extra plug for the transmission (the automatic has two I only have one on my tranny). So here is the question, can I just leave the harness on the engine and use only one of the plugs or should I take off the harness and replace it with the original one for the manual transmission. I'm leaning towards the first as it would be a lot easier and actually seems like it should work however if anyone actually knows the answer or has done this in the past I'd greatly appreciate the info.
