Starting to go through my wiring!

The electronic ignition must be factory as the wiring was under the factory wrap, what is outside the wrap though has seen better days - it gets power from the coil, taps into the VR, sends power to a field post on the alt, and runs to the pass fender well to the box, then to the resistor right behind the box

I had to unwrap it so I can test fit it and shorten/lengthen the necessary wires for the big block

The new Mancini electronic harness I bought didn't come with instructions on how to wire it.. has 2 large grey wires for the dost, 1 small Green, 1 small Blue, and 1 small Black - none of the wires on my harness match but the Green
