Well I'm trying to swap my 95 4.0 OHV explorer engine with a 98 4.0 SOHC explorer engine. I'm hoping to use my 95 wiring and sensors on the new motor to avoid dealing with the ECU. So far I beleive I can make most of the old electrical system fit on the new engine. The only problem I'm having is finding a way to make my cam sensor work. My old OHV engine has a three wire hall effect sensor with: (+12v line, -/ground, and a signal wire)the sensor sends a +5v pulse to the ECU when at TDC if I understand it correctly. The sensor on the 98 SOHC engine is a prox/electromegnetic pickup sensor with two wires. I have concluded that I will not be able to use the old sensor for this so I most find a way to make the new sensor work or find another alternative. I know very little about the new sensor, I have the wiring diagram for both motors but do not know the specs (voltage input/output, pulse width, on/off time) for the new sensor. If I can just get a +5v pulse at TDC with this sensor it will solve my problem. I've been thinking about soldering a resistor on one leg to drive a transistor out to another resistor for +5v but I think I'm taking it to far. Any info please help I'm losing my mind, I need any help I can get.
