I was thinking of doing the same after reading some threads. I may just go old school and put two switches on the console somewhere. I only plan to have two aux needs.
Any updates on this build? I'm looking to upgrade my panel to the one with the aux switches as well so I can run a lightbar in the front bumper. When I put in that part number for the panel it pops up but there is no info for it. The one that does come up and being a direct fit looks different...
