Yeah, both the pocket and the panel are universal. They sure made it seem like it goes to the metal dash frame on the TJ they demonstrate it on, so I was expecting it I go in the dash hole, not the trim. Anywho, it works.
Great minds think alike on the led. I actually texted my buddy an hour ago who knows a bit more about electrical than me asking if a resistor on the ground would dim it or not. He hasn’t gotten back to me yet but sounds like you answered it for me, so thanks for that. I’m accustomed to putting resistors on the power to dim things, which is precisely what I did on my side markers to run them dual stage low and high on a single “filament” led bulb. Except in this case, I can’t resist the power side because that is the source for my accessory.
I’ll probably buy a kit of cheap resistors and play around with different ohms and watts to see what I like best. 1W 100ohm worked really well to tone my extremely bright side markers down to perfect calm brightness at night. Worked out well because the bulb brightness by itself is very bright at night and good enough during the day too. I imagine a similar size resistor would do it nicely, but of course will need to play around to fine tune it.
