Need some help wiring some rocker switches in Phoenix

Any one have experience wiring up rocker switches for use with LED light bars in the phoenix area? I bought my truck with two light bars mounted and wired but one of the existing switches was installed in the coin tray and is a simple 3-wire on/off toggle switch. I'd like to order one of the nicer dual LED rocker switches and have it wired into my dash lights and installed on one of the blank switches terminals on the left of the wheel above the coin tray. Any insight would be much appreciated.

I was going to order from this site and go with a CONTURA V. Any recommendations?

I can help you when the time comes! I have a 6 switch panel with carling switches that I installed by my self. It's. Really simple.
