I installed a 97-98 engine speed sensor/ crank sensor to run my tachometer. I have already ran a 5 volt power, ground and sender wire for it but I can't find the pin out.

here is a pic of the plugs the one with the 123 is the harness side the the other in the sensor.

I need to know where the power, ground and sender wires go on the 123 plug.

Here is a pic of the sender I am using.
