If you’ve ever tried to add auxiliary switches to a modern truck, you already know the pain—running wires through the firewall, fighting factory grommets way back in the abyss, and dealing with giant conduits and bulky harnesses. In this video I review and install a wireless 6-channel auxiliary switch panel from Magnolia Advanced Designs, and it’s one of the cleanest ways I’ve seen to solve the worst part of accessory wiring on 2019–2026 GMC Sierra and Chevrolet Silverado trucks. I walk through what’s in the box, how the control box is laid out (fuses, power/ground, remote turn-on wire), and why 60 amps on a 12V truck is honestly plenty for most setups—especially with LED lighting. I do a bench-style demo by powering it from a lithium battery, then I show it installed inside my truck on the A-pillar grab handle using the provided bolts. No drilling, no cutting, and the strobe/flash button is a really fast way to flash whatever circuits you already have active. If you’re tired of messy wiring and you want a factory-style interior integration, this wireless setup is absolutely worth a look.
