Summit Technologies Raptor button system.

This is the easiest and best system to use if you want to have controls at your finger tips.
I currently use it for aux fan, diff cooler, coolshirt, and the aim display functions.
I might be going a different route in the very near future and wanted to give people here first crack at it if I move on from this set up.
PM and I can discuss more.
Thanks.
