Huh? You only need one power plug mate (the 3 pronged one). All it does is takes the headlight switch signal to turn the hid relay on, which then fires up the 2 ballasts. Take a picture of the whole kit and wiring, layed out on the floor, and I'll tell you where the connections should all go. How does that sound? ;) I agree though, HIDs can be a pain, Im just about to send off a wiring loom for my current set as theres a problem with it, leading to one of the bulbs not firing up, even though both bulbs and ballasts are working fine. When you run the Hi/Lo Xenons needed on the glanza, you get these problems as the loom is more complicated.
