Strange,Thanks for all your help, but may I add something?
I just spent the last few months trying to get my LED Roam lights to shut off automatically, to no avail.
I would go back and re-read your uxcell relay instructions, but no success?
Then it occurred to me that you may not have had the optional factory LED Light package, but I do.
Once I wired the Roam LED's directly, by-way-of a fused link to my interior LED wire, all was well!
I suspect that my factory interior LED lights didn't draw enough power to trigger the disconnect function of the uxcell solid state relay?
With my Roam lights wired directly to the interior lights without a relay, my Roam lights still dim quite nicely in the same fashion as the interor dimming qualities.

I've done the install on both LED and Non LED package Jeeps. Really the main difference isn't in the LED package but whether or not you Jeep came equipped with the "mood lighting". On vehicles with it there are three wires to the footwell light rather than two. In both instances the wire color I tapped into was the same and the step lights functioned the same.
