The dash location for the fuse block on my 24 was not pre-drilled. I simply drilled holes in the plastic backing and zip tied the fuse block in place. It's roughly in the same area. The plastic knee bolster panel still fits nicely and hides 98% of the block. Here are more detailed shots.
I think I have found a spot to use as a trigger for the high beams (K9 BCM X2 pin 32 <wh>). Just finished putting a light bar on my 24 Ulti-D. I installed the upfitter switches and am happy with the way it turned out. I ordered some tap-splices. I'll let you know how it works out.
