I recently searched (online) for a programmable touchpad that could control a wide variety of functions (via relays). My dream would be to removed all the switches that control the aux lights, high idle and air compressor and control them all by a touchpad.
So...long story short, find or design one of those, install it and let me know where you found it and how well it works.
If you're not that inspired, I recommend:
Aux light switches
Locker switches (if you have them, or want them)
Winch power switch
uhhhh...look at the online store here instead
