Interior LED light / Electrical Question

I need some assistance....after looking at the some of the LED interior light mods, I decided to try it. Not the best idea. The 7.5 amp fuse blew and the lights would sometimes work and sometimes not. I switched back to OEM (same thing, they may/may not work). My bigger concern is the warning lights that now stay on (TRAC, driver seatbelt (even though it's on) and passenger airbag - with no one in the seat). The key fob (lock/unlock) also stopped working. I've looked at numerous fuses and they all look good. I've checked some of the relays and they all seem to be good (according to the Ohm meter). I'm hoping someone may have a solution. If not, I'll take to to the dealership.
