Sorry ... was in a hurry earlier. Hard to take good photos in poor light after everything is done.
Hopefully this all makes sense.
1. The SP9100 is mounted to the fender wall to the lookers right of the battery. Hard to see under the wires. It fit perfectly.
2. There is a large rubber grommet on the firewall (shown circled in the picture - you can barely see it). I cut a slit in that grommet and shoved all my wires through it. It is sort of a multi layer grommet - I'm not concerned about dust / moisture ingress at all.
3. The zoomed out photo showing the ARB compressor has an arrow pointing to the general location of that grommet. The zoomed in photo is the best I could do to show the grommet.
