3rd gen radio reception got bad; fuse?

Hi all. I've been Googling all morning and cannot find an answer.

The other day I was installing some aftermarket taillights. Apparently, if you plug them in backwards and turn on the lights they blow a fuse. No big deal. Replace fuse and try again. All done. All the lights are working.

Well, since then (and I mean immediately after), my FM radio reception has become terrible. It was not this bad previously. From what I can tell there's a signal booster someplace. I'm imagining there's a fuse related to it and that I blew it. Anyone know which one it is connected to? As far as I can tell, everything else is working.

 

I figured it out. It's not any fuses. It's the LED taillights I put in. Not bulbs, whole light. I've had this issue before. Some ferrite beads fixed, but that was one light, not an entire taillight. I'm going to email the manufacturer and see what they say. Just leaving this here in case anyone else has the same problems.
