Any pics during install process you can share?Hello TheDocAUS:
I used the anchoring of the fastening ring at the rear right (standard). I made a bushing to bridge the recess. This is connected to the rear plate of the air compressor. If the distance is correct, the side bolts/nuts of the compressor can be fastened to the back plate.
I did not want to drill any holes etc. The only thing I had to change was the cable harness feed-through in the lower small cover. I routed the wiring harness to the front of the auxiliary battery.
