a Frenchman who needs advice for GM HEI MODULE!!!!

Hello

I'm changing the harnesses of my Duster from 73 (slant six)
I bought this harness
14 Circuit Plymouth Restoration Wiring Harness

I would like to reduce to the maximum the wires in the engine compartment
and I would like to go through a GM HEI MODULE to remove the ECU box and the ballast resistor.

With you advice to give me for this operation?
is it achievable with this type of harness ??

thank you for your answers and for guiding me in this operation.
