The RACEWires remote start switch adds convenience to bumping the engine over and checking converter bolts without the need to permanently mount the switch. You can simply wire the provided 6’ 2 wire harness to your existing neutral switch and run the 2 pin connector out to the engine bay. When you want to adjust valves or check converter bolts just simply grab the 3’ start switch harness out of your race bag and plug it in and your ready to go.
