[snp_ethan]

ok, they are having a HID groupbuy and I got a set. but the damn thing needs to be connected to a pos and a neg poles, now, I got a tester but I read the whole manual and I have no idea how to use it to find out which one is which, i am waiting for the answer... for my car is waiting until I find this out...
help plz.
oh yeah, either that or just tell me which one is neg and which one is pos for the low beam (zenki)

no one yet? c'mon, im waiting for an answer before I blow them up,.,,,

turn on lights, connect neg on voltmeter to any ground (battery, engine, etc), connect positive to one of the 2 wires for the headlights....also, get an FSM and you wont have to ask what wires go where

You never heard of black as ground?

There's two wires behind the blub, is it really that complicated to figure out what they are?

well, i got it solved... but yeah, i know black is neg/ground and red is pos..
but im asking about the harness , by that i mean the wires that are attached to the bulb , the low beam bulb, those have no colors...

The have no colors? So what are they, transparent?

Seems strange, every S14 I've worked on has had red/green (HI, Pside), red/blue (LO, Pside), red/black (HI, Dside), red/yellow (LO, Dside), and black (GND) at the headlight plugs. Guess yours just has bare wires throughout the harness or something.
