I picked up a harness from RJM injection it had a power wire to the battery for the ecmAnd one wire goes to the ignition side of the switch and one wire goes to the run side of the switch I didn't know if I just hook the white wires from the engine compartment to the silinoid if that Would work the starter with the ignition switch or if I have to run a separate wire from the switch to The silinoid to put power to the starter from the switch
