Help installing 07 sti headlights in 07 wrx

Corpuz04 · 03-28-2011, 02:40 PM

Now I traded an sti headlights and plug the main harness. Now theres another harness on the headlights near the gray main one but I can't plug that to nothing. So I try to turn them on but turn signals only work. What do I need to do? Heard people said there plug in play and some people say I need a harness lightwerkz have one. What should I do? If I have to get the harness I will have to trade someone for Wrx headlights

looks like your solution is in your post: call LightWerkz

otherwise, this has been done many times before. i'm sure a quick search would yield you some answers. sorry but i only did limited research on this, i decided to stick with my WRX headlights and install TSX projectors.

That second plug is for the headlight leveling motor. You won't have the setup to run it so just leave it.

I think the wiring pins are different between the WRX and STI. Pull it out and double check all the pins.

Although it is better to pick up a proper harness to power the ballast.
