Does anyone know how to install 04 JDM STI HID Headlight on a 04 WRX. I can't find anyone who has done the swap. Will I need new wires? Do I need to cut my exhausting wires or is it plug and play?

Thanks for the help.

I know how to swap the actual headlights but I don't know anything about wiring.

I know how to swap the lights too, I just want to make sure I wire everything correctly. I couldn't find any other info on this particular swap.

I ordered this wiring kit: HID Projector Headlight Retrofit for Subaru, Honda, BMW, Scion and More | LightWerkz.net

I bought the STI harness from Lightwerkz but I can't figure out where the wire taps go? Does anyone know what wires to tap and can you upload a pic?

you should only be using the High Beam plug, and 3 pin plug that goes to the blinker and marker from your car into the STi headlamp. The Lightwerks harness goes straight into the Ballast on the bottom of the headlight. You will have a plug from your car that would normally plug into the LOWBEAM of your WRX headlamp not plugged into anything but you WILL use it to tap the Lightwerks harness onto. *optional* You will be left with a 6 pin socket on the STi headlamp that is used for in-cabin headlight leveler adjustment.
