When I bought my 04 private party it had a wireless remote in it. It has 3 switches and runs the turbo lifesaver and my pac brake. I'm going to hook up a couple of lights too. It was mounted to the steering wheel but I'm moving it to the shifter. It's pretty cool and works well. No fishing wires and cutting holes in the truck. It's about the size of two quarters lieing side by side and 3/8" thick. It switches the relays on so there isn't a big draw on the system. I'll know more about it when I hook up the lights but for now I'm really happy with it.

 

With the right receiver, you can get up to six functions. Check my gallery if you want to get it to operate more stuff.
