Bosch Hid

I have a 4runner 98 and need help installing my HID headlights.

I do not know how your kit is composed. but on mine lights plug right up ballast then there are two son, usually red and black. the son must be spliced into your son's flagship factory. red goes to the hot side and the black goes to the ground .. Some kits have a power relay box to protect the wiring .. The box has two hot son that the son of the battery connection to the ballast then go to your son's flagship factory to act as a switch, but your main power comes from the battery .. Now, if your bulb factory was one bulb being bi it had both high and low beam .. you have 3 son and you need to know which wire is low beam and high beam and floor .. Tell me how your package looks then I'll change my answer to give you a better explanation ..
