Putting my 245 on running a holley red used this in the mirage with a toggle switch but I want to run a relay on the allison there's one in the back from the guy that had it before I want to run the power off the power head to activate relay or purple at key?

Hot side of the relay to 12V from the power head, control wire to turn on the relay to key on power

Have find a ignition hot on the power head to activate the relay he's already got the relay hooked to battery hot just got to see which wire gets power on the power head when key is turned on

Found the purple wire its taped inside the engine harness plug just sliced into it now turn key on relay kicks in instead of going. Up to the keys switch
