For wiring - it's pretty straight forward.
Red = 12v positive
Black = GND
Switch = spliced into the 12v POS wiring for signal inturrupt
Relay that is rated higher than the amperage of the lights you're installing
I can work up a simple diagram if you need it... But here is a good article online about wiring

A good way to get started is to head to Sears or Radio shack and pick up a wiring kit that will include some connectors, crimpers / wire cutters, electrical tape. A big help for wiring is to have a multimeter on hand to check out any problems you encounter.
