Headlight Plug: Which Plugs are + & -?

[improved]

Hello gentlemen,

I'm replacing the front headlights with H.I.D. bulbs and E-Code housings.

I was looking at the back of the H.I.D. harness plug, the one that connects to the stock light harness, and from what it looks like the two positive wires on the back of the stock harness are in different spots than the H.I.D. harness.

Unfortunately, I have a hard time reading the electrical schematic on SONIC. Does anyone know, which wires are which on the back of the stock Bulb connector.

Thank you,

Matt-

try it one way, if the hids dont light up, switch it. thats what I did.

WOAH! Do NOT just try one way and then the other. You can kill the ballast or the bulb feeding + down the - wire.

Get out your trusty voltmeter - you do have a trusty voltmeter don't you?
connect the - wire to a common ground
Turn your low beams on and touch all three prongs with the + wire until you get a reading
Then turn your high beams on and touch the other two prongs with the + wire until you get a reading.
Then read this link http://www.danielsternlighting.com/tech/bulbs/Hid/conversions/conversions.html BEFORE installing those nifty HID bulbs in a halogen housing.

haha... it worked for me.....

Im not sayin its the right way. It just worked for me

the ones going up and down " I I " should be the high and low beam power
the one going across " - " should be the common ground regardless

I'll use the voltmeter. I just need to find my battery(stupid garage.)

BTW, the wires going into from the body harness plug are as follows, Pink/black(I assume ground,) Pink/white(Power1??,) Pink/Blue(Power2??.)
