I have 2 systems. PSI harness for the engine and Painless for the rest, lights radio etc.

Since the PSI has everything on the engine covered I'm thinking I won't use several wires from the Painless harness. they include:

electric choke.

regulator exiciter.

alt. regulator - - PSI has wires that plug into the alt.

coil + ignition- hot - LS has 8 coils all plugged into PSI

temp sender - PSI has a plug into the temp sensor

tachometer to coil.

oil sender - Dakota Digital has a seperate oil sensor and wires.

cooling fan relay - PSI has a wire for that relay and the other is to switched hot

I'm thinking I won't use these wires, thoughts?
