I have 2 quick questions I am hoping you guys can help me with. I have an extra MOPAR ECU box I am wanting to use on a non-Chrysler motor in a race car I inherited. I know... I know... I should get a Chrysler but I don't have the money right now and am having to make due with what I have. Below are my questions:

1. Do one of the 2 ECU wires going to the distributer just carry + current to the distributer? Essentially I am needing to know what the wires attached to the ECU posts 4 & 5 do (see pictures).

2. and a related question is, what is the color coding for the wires that go into the distributer? This is an out of the box MOPAR distributer with wires. I believe the wires going into the distributer I have are black and red or black and brown. See photos for more information.

In the attached photos I have tried to circle in yellow the areas I am trying to understand better.

As always, thank you very much for your help!
Bill

Actually none of the two wires going to the dist pick-up coil have + current on them as the pick-up coil is almost what I would call a small generator as it creates its own current. You can use a low scale voltmeter and check them as they make a small voltage of about 1.6 ac volts when turning. The magnetic field gets stronger and cuts across the pick-up coil windings everytime the relutor blade passes by the pick-up coil magnet. But they do need to be hooked up the right way. I can look up the wire colors tomorrow for you as its late now and I am going to sleep. Ron
