Headlight Wiring

Just wondering if anyone knows which wires are positive low beam, positive high beam and ground, i bought a hid kit but apparently gm's are wired different than ford or dodge

i don't know the colors offhand, but checking the sockets with a testlight should give you your answer.

now, it is possible that the headlights are groundside switched, the S-Series was, just keep that in mind, and if the kit requires the blubs to be power switch for some strange reason, a relay could be used.

your right on that it is a switching ground, the middle wire is full time power, so off to the drawing board again to figure something out.. thanks
