no, it just plugs in to the same sockets as the bulbs, so it should act the exact same as stock... that's why i am so confused.

now i am confused, i went out there and tested some stuff with my multimeter, and i get power at, and through the fuse, but not at the light socket...
the only thing i can think, is this truck was towed behind a motorhome or bus or something before i got it, because it's got a lights set up rigged up for the front (so the motorhome's lights go through the trucks lights), it's also got a spot cut out of the lower bumper plastic for a tow bar.
so i figure maybe they screwed up the wiring when they did that... i'll have to look deeper in to it when i have time/warmth.
