Default Wiring MSD ignition question
Is anyone familiar with whether or not anything in particular has to be done with the existing ECM wiring bundle in the engine harness when using the MSD system? It seems that there is a fused ignition wire (#128) in there that could be used for the MSD switch wire and a tach wire (#132) that could be used for the MSD tach lead. Wondering if the remaining 4 existing ECM wires (#185,186,187,189) can just be sealed and ignored without incident ?
Thanks for any input here, Ronnie
