Re: HOW DO I ADAPT A 3 PIN CAM SENSOR TO A 2 PIN CAM SENSOR

Do you have a different year engine in your 1999 Explorer?

The procedure I located looks something like this. I hope this works for you.

The difference between a 2 wire and 3 wire sensor is the power wire.

Three wire sensor:

1. cam sensor wire to pcm
2. sensor signal return (ground)
3. power

2 wire:

1. sensor signal return (ground)
2. power/sensor wire to pcm

The two wire gets its ground from the SSR (light grey with red)
and its power from the cam sensor wire from the PCM (dark blue/orange).

You can easily install a 2 wire sensor into a 3 wire block and vise versa, you just have to tap into the solid red power wire Acc 12V+ to all sensors.

Good luck.

Pardon my question, I have a 98 windstar that I am dropping a 2003 engine into.   So, on the 2 pin camshaft sensor, you would take the power wire from the 3 pin and connect it to pin #2 on the 2 pin?   Putting the reference voltage straight onto pin #2 which is how it would be on the 2003 PCM.
