Watch me figure out how to install a switch panel with push button start in my truck, The kit didn't come with instructions, so maybe this will help you figure out how to install one in your car.
DISCLAIMER, remove your battery BEFORE doing any wiring in your truck/car!
Also, I didn't use the relay included with my kit. Since there were no instructions, I can only assume that the relay is to make the start button hot after the ignition switch is flipped. The result of this is you can hit the start button at any time, and the truck won't start unless the ignition is flipped. Oh no.
