Finally figured out where this thing is to be mounted. Course there is no literature anywhere on installing this system yourself. So I got to looking around on the underside, AMC is clever as I finally figured out what the three dots are for on the upper firewall and got to thinking, AMC thought ahead and put dots on where to drill holes and holes for bolts to go through etc. I looked up at the floor and saw two holes and the seat belt bolt that caught my eye, looked to the other side and noted there was only one eye by the seat belt bolt. "This has to be it." Looked at the parts book and found the bracket to have two bolts holes going through the bracket but to where.
This spot has to be it, I cannot see this going anywhere else. So now I have to make an arm that will bolt to the sensor and push rod so that it will actuate when the XJ is low to trigger the compressor for more air.
