I, did come up with a idea for this. But, haven't had time to order the parts and try to wire and mount. No, time. Also I am in ga. May take another look before fall gets here.
Do this with a few months ago. Worked fine. MAKE TO TURNOFF MAIN DISCONNECTION FRIST. DO NOT TURN BACK ON MAIN DISCONNECTION TILL AFTER TRUCK IS UNPLUGGED.
