Wiring is definitely not my strong suite. I'm trying to wire up a heat exchanger fan for key on operation. Lonny has laid out where to tap into the bcm plug to get power. It is 2 wires that get wired into one. But one of the wires in the terminal in my BCM plug appears to be used on something already. The second one is cut. The harness was assembled by DF, so I don't know what it goes to.I'm running a heat exchanger in the engine compartment, so I will be running it to the back of the car. Is there a different terminal I can tap into that will be powerful enough for the fan?
