I've got the KE-3100-K installed on my 2006 Dodge Ram 3500. The compressor is a York 209 with a 25-501939-D Clutch. The on/off switch is 90psi on/120psi off. The air tank is 8.5 gallons.  With the kit is an KE-AM6 air manifold. I've got everything you need here for on board air. I hate to get rid of this kit but I'm going to be trading my truck in soon on a 6.7 Cummins and I'm not gonna be able to use this on it. I've got lots of pictures so if anyone is interested i'll email them to you.I've also got some video clips I took and I'll post them pretty soon. I'm going to be removing this kit from my truck in the coming week. If anyone wants to buy this let me know and we can work something out or if you have any more questions My email is sbaker7890@hotmail.com. Make me an offer.-Shaun Baker
