Hey there. At first I was a little nervous about it because I didn't want to blow the fuse because it would kill the headlights. The CCFL's draw such little power that it worked fine. The headlight fuse is in the interior fuse box (driver's side). I just tied the wiring from the power inverter into that fuse...and it worked perfectly because there is even enough room to fit the actual power inverter in the fuse box itself.
