got a 1986 f150 as a mud truck that has no interior but the seats and wireing harnes instead of having the wireing harnes with all the wires everywhere i want to install a push start and toggle switches. What would I need to hook the toggle switches up to? I would expect i need to hook up the fuel pump and distributer and thats it. and what would I need to hook the push start to and can I run that as the only wires in my truck?
