Hooking up a two prong switch for the TQ lock up and wanted to put a indicator light on the dash. As far as I can tell the switch is to ground so if I hook up power to the light and the ground to the Acc side with the TQ wire it should come on when ground is applied! My question is I think the ground wire for the light will try and find ground thru the TQ wire so this would be bad! Would a one way diode stop the flow back thru the TQ wire? Or would it also be a pass thru for ground?
