I was provided the wiring harness for the AiROCK system with this kit, since that was going to be sent later during the prototype stages. I don't have any photo's of wiring up the compressor, but it was fairly simple to wire. I just went switched power to switch inside Jeep, to pressure switch, to relay, from relay to compressor. That way I had control of turning the compressor on and off.

Connecting to Power:
Mark the wires, and remove the fuses from each holder.
Attach the power wires to the power post of the fuse box, or the positive terminal of the battery. You will need a 13mm combo wrench for the power post or a 10mm combo wrench for the battery terminal
Connect the ground wire to the negative battery terminal. You will need a 10mm combo wrench
Carefully remove the taped on fuse tap.
Install the fuse tap on a spare fuse. The tap will go on the load side of the fuse when installed.
Connect the fuse and fuse tap in to a switched circuit in the fuse box. This will deenergize the compressor clutch when the engine is shut off saving a load on your battery. I used
 
Installation compressor run indicator LED:
Off Road Only included an indicator to show when the compressor was running. One of the leading causes of compressor failure is excessive run time. Normally if you blow a line it is quickly noticeable with a bag going down, or complete air loss of the system, but if you have a leak that causes the compressor to stay running you might not hear it driving down the freeway.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work. While I have spent many years working on mechanical systems, I am not an expert, nor do I pretend to be one. I hope these write ups have been useful to you.
