mines hooked up to the headlight fuse, sense the fuse box is right there..i assume u have it on ur pillar? just run then down behind the seal and down towards ur hood release, and pull the fuse for one of the headlights and wrap it around one of the prongs on the fuse and push it back in..that way they cut on when u cut ur headlights on..now someone might wanna say rather or not that is smart, because i really do not know, but i havent had any problems in over a year with the lights nor the headlights, so i dont think its a problem...and for the ground you just find something metal to ground it to, i believe there is a dimmer wire as well? d*** i so forget what its hooked to, id have to get back on you on that one
