I am currently swapping an 5.9 magnum & A518 into my car. I am keeping the factory EFI, Computer etc. My current hitch is the speed Sensor.

The OEM one in 94 was a 3 wire unit with no provisions for a speedometer cable. I want to use the factory Speedo but need the signal for the Engine Controller.

I picked up a pass through speed sensor off of a Dodge van but it only has 2 wires instead of three.

Is this adaptable or do I need to look elsewhere?
