converting to electronic ignition

Okay, need some help with electrical issues. One of the previous owners had started converting the 70 Duster to electronic ignition. He put the electronic ignition box and a harness in, but my issue is that it appears the bulkhead connector plugs don't match up to what is on the interior wiring.

Any way to identify what the harness came from so I can get a diagram of the bulkhead connector plugs, or should I just start running wires according to the wiring diagram in the service book? If I run new wires, can anyone help with what changes there are with an electronic box in place of the original points distributor?

Thanks,
Scott
