I am wring a powermaster into a new harness which I am building. There are 3 wires coming from the C100 bulkhead 12g Power, Brown Fan relay power and the tan/wht waring light. The PM motor shares the brown fan relay wire with the fan relay and the 12g Red wire with the coolant delay relay both of which I have eliminated. Can I just run the 12g red power wire directly from the fuse panel and use the brown fan relay wire direct to the pump? Or do I have to run a separate relay with the brown wire as a trigger and the power coming out of the fuse panel to the relay and back to the PM pump?
