Not sure if this is the right forum, but here goes....

I have a 6.7 with auto and I want to add air lifts. To do this, I have to run control wires and air lines through the firewall. I wanted to run it through the wire loom boot, but there isn't room . But, about 6 inches to the right (towards the truck center) of the firewall there is a 1" diameter hole covered in the engine bay with a plastic plate. It is held in place by two very large nuts and bolts, so my assumption is this is for an accessory or option I don't have.

This would make an excellent place to run the cables. But, before I drill through this, anyone know of any reason why I shouldn't? I have no idea why this plate is there in the first place....

Thanks for your insights.

Clutch master cylinder would normally mount there. Do what you want with it! lol
