I was at a car show the other and I saw a guy with a car that had a pretty cool idea. He had switches controlling a lot of things. He had a swicth for his head lights, windsheild wipers, and amp, all mounted in his dash. I saw them in auto zone for like $10 each.I thought It was really cool. Has anyone ever done this or how hard it would be to install. It looks like the flip swicth people use to turn on the there NOS.
