I purchased this compressor to mount under the hood of my Chevy Colorado. I ordered the compressor and was surprised to have it the next day. I had used the free shipping that stated 5-8 days. I was very surprised. I opened the box to find the compressor and parts to be in excellent condition. The box contained everything needed for installation. It even had ring terminals and connectors to wire the harness to the battery. I was very happy with the wiring harness as well. The harness that is supplied with the compressor is designed for lockers, but I am using this compressor for tire fills. The harness was labeled very well and instructions were clear. I had no trouble with the wiring harness. The harness is plug and play. ARB even leaves one plug disconnected so only a small hole has to be drilled to get the switch to the cab area. I simply taped off the wires that I was not using. The wiring had a nice looking switch that is designed to be recessed in a small cut out. I found the switch to be good. The location I mounted the compressor was very tight, but the mount is made to pivot. I was unaware that the compressor body and manifold tube can also be rotated to facilitate various mounting locations. The compressor itself was heavier that I expected, but that was great. The compressor feels well made. I mounted the compressor and made the appropriate wiring connections under the hood. I actually mounted the switch under the hood as well. I used a small plastic gang box used in home wiring and used a Dremel Tool to route out a hole for the switch. I then used a metal plate to cover the box.I was then ready to use the compressor for the first time. I hit the switch and the compressor fired right up. The compressor only ran for about two seconds and shut down. The compressor comes with a pressure switch that shuts down the unit at around 90-100psi. The manifold tube is very small and it gets to that pressure very quick. The manifold tube also has a built in pressure safety relief valve just in case the pressure switch fails. I am not sure what pressure is required to permit the safety valve to operate.I had to source my own fittings to use the compressor as a tire fill unit. I did not purchase the kit offered by ARB because I can build it cheaper myself. I spent an additional $15.00 to make a manifold for my tire fill kit. I had to buy several pieces due to my mounting location under the hood. I also suggest to anyone that purchases the ARB tire fill kit to buy some Teflon tape. I completed the procedure and was ready to fill a tire. It should be noted that I already had 50 feet of 3/8 air hose and fitting to use the compressor. I wanted enough hose to reach from the engine bay to the tires on my travel trailer without uncoupling the trailer.I had been carrying a portable air tank in my truck that holds 120 psi. I decided to test the compressor by filling it up. I turned on the switch and watched the hose fill with air. The compressor then promptly shut off as designed. I filled my air tank from approx 40 psi to 90psi in approx 1 1/2 to 2 minutes. The compressor stopped filling at 90 psi. I was still impressed at the speed given the size of the compressor. I filled a car tire from 10 psi to 32 psi the next day and was equally impressed at the compressor. I think it was a wise investment and would buy it again if I had to go back.My installation took my friend and I two hours to complete. I had a small area to work with and had to "build" some tools to install some small screws in a tight place. I think my installation time was long, but I had a unique mounting location. Anyone with basic skills could install this compressor easily. I needed to drill three holes. The mounting plate has four holes, but I didn't use one due to mounting location restrictions.This is a good compressor and I hope to use it for many years. Good luck.
