I was trying to convert my usdm foglight harness to plug into a JDM switch, but I think I screwed up somehow. Now my parking lights don't work, the only thing I get is headlights. No taillights, sidemarkers, guages, interior lights, nothing. What should I check? I've been checking my fuses, but I think it could be a relay or something.

 

you've checked all of your fuses? it definetly sounds like a blown fuse...
