Aux Lightbar without the High-Load Panel

I’m looking for someone to sanity-check my wiring plan.

My Quartermaster does NOT have the high-load auxiliary switch panel. I installed the Ineos cross-bar light bar (given to me), which needs a 25-amp circuit. My idea is to use Aux Switch 1 (rated for 10 amps) only to trigger a 30-amp relay, and then run a dedicated power feed to the relay with a 25-amp fuse for the actual light bar power. Does this wiring approach make sense? Not sure how I run the power to the rack yet, that I will figure out later. Appreciate any thoughts on this!

Welcome to QM club and that make sense. I have aQM and live up near Seattle.
 
I asked my local auto electrician how easy it would be to add more accessory circuits if I bought a base Grenadier while I was looking for a replacement. He anticipated that the Grenadier would be easy as he could use a mixture of generic and OE parts to do almost anything. He would have used the factory wiring paths as that would be simple and not require holes drilling.
