Automotive Help for Subaru WRX

gtfaded · (#1 (**permalink**))

Hi, I have a 2002 Subaru WRX that I recently purchased Japanese Domestic Market headlights for. The lights come stock on the JDM Subaru Impreza WRX Sti. I am running into a problem getting these lights wired up correctly to my USDM WRX. Here is a pic of the lights I am refering to.

I know this isn't an automotive forum but I have searched the web for weeks now, on various sites and forums as well as posted in Subaru specific forums such as NASIOC.com and lighting specific forums such as hidplanet.com with no luck.
It may be a long shot but I am hoping someone here may have knowledge of cars and be able to provide me information or may know someone who has knowledge of Japanse vehicles that might be able to help.
The question I have is, the plug coming out of the light, that goes to the internal ignitor in the light, has 3 wires on it. They are colored Brown, Orange, and Black shown in the pic below.

I need to know what each colored wire represents, ie. Orange = ________,
Brown = _______, I know the Black is the ground. One of the wires will be a positive and one will be a negative just not sure which is which.
Any information anyone can provide is greatly appreciated.

black - ground (ie negative)
orange - 12v
brown - signal

try it, if you blow a fuse, replace it, try another combo

Hi & Lo

Orange or Brown + Black = Hi beam
Orange or Brown + Black = Low beam

Thanks for the help but the above post can't be right as the plug shown above that goes to the ignitor only goes to the low beam HID projector. The high beam is a separate bulb and wires.
If I wire them wrong it won't be a blown fuse it will be a blown 150$ ignitor or ballast. But again thanks for the attempts.

double post sorry

why not hook up a multimeter to see which direction the current goes?

The light's themselves would need to have power. I know the wire pattern that comes from the car, just not the configuration of the pattern on the light's plug.
Seeing how the car is domestic to Japan, I was hoping to find someone in Japan that may have the resources to obtain the plug's pinout or configuration. Or perhaps a website to review, or person to contact. If it were a Ford or a Chevy I would have been able to obtain the knowledge without effort due to them being domestics here.
Like I said it's probably a long shot.

multimeters work on unpowered devices just fine ...
