If he does that, won't he still have the problem of the relay sticking on that he already has since all he's doing is replacing the keyed switch with another switch?
If he wants to use the existing relay and wiring harness without modification, wouldn't he have to interrupt the heavy power supply wire to the OE relay with another relay so that all current to the OE relay is cut off with the new switch/relay combination?
