I've checked through many questions and replies...but I don't see a definative answer. I'm putting a 1998 4.0 ohv motor into a 2000 explorer and I'm now faced with a 2 pin connector from the original wiring harness, plugging into a 3 pin connector on the older motor. Cam positiion sensor. Or vise versa..doesn't matter. What I am trying to find out is whether I will have to replace just the top with the connector, or the whole shaft and gear. One person previously suggested that just the top could be "tried", but it didn't sound like anyone knew for sure. Of course, it would be preferable to fix this using just the top part... removing and getting the gear and shaft right sounds like a bit of a challenge. Thanks.
