Installing a crate ls3 getting ignition wiring figured out (forgive me this is the first time Ive installed any engine)
have two wires one labeled constant for ECM
the other says switched 12V.
Dont see a ground wire on the harness.
I was wanting to run a battery cut off switch
questions:
Do I wire the constant as a constant... dont run off the battery disconnect bus bar? Or can I shut the ECM down every time I shut off the buggy?
Is the switched 12v how I would shut the engine off?
Is the ECM grounded through the case to chassis connection?
