Use the blue wire with white stripe for amp turn on. If you're not sure about the dimmer/illumination, just tape them both off as they're probably not the right ones. I've only ever hooked up the reverse wire to the rear reverse light but then again I've only had to do it for sedans and coupes. If you're not using a rear view cam, don't even worry about it. Car speed input goes to your VSS wire. You'll have to look that up because I don't know off hand what wire it is although it's usually found on the back of the dash cluster.
