Current Stock: 10 pair as of June 7, 2018.
Due to lower demand, I will likely not be ordering additional parts to make more once my stock is gone.
Harnesses in stock usually ship within 1-2 business days. Harnesses built to order (if I have no stock) usually have a lead time of 2-3 days unless otherwise specified (usually due to waiting on parts).
NOTE: I will not be shipping harnesses between June 11 and July 29. All harnesses ordered on or after June 11 will ship July 30.

If you're happy with this mod, please don't forget to thank NASIOC users Power6, clamsjager and DDS4 for helping me make this possible. You can read the forum posts above to see all we went through or if you want to learn how to build the harnesses yourself.

For early production harnesses (shipped long ago) the wire color varied depending on what I had available. As orders increased, it made sense just to buy huge spools of green and white wire, so all harnesses shipped from this point on will be green and white like the pictures and forum posts. I have left the section below for people who may still have an old version of the harness and still need to install.
IF YOUR HARNESS HAS WIRES THAT ARE NOT GREEN/WHITE:
You will need to reference the table below as forum posts all show white/green wires, including Power6's connector wiring pinout post on the right side of this page.
Wire Color Designations:
White/Green Wires - White is Positive, Green is Negative
Red/Black Wires - Red is Positive, Black is Negative
Yellow/Blue Wires - Yellow is Positive, Blue is Negative.
For example, if you got Red/Black wires, the Red wire will install in place of the white wire (pin 1 on the mirror connector), and the black wire will install in place of the green wire (pin 5 on the mirror connector) - see the connector wiring post on the right side of this page.
When upgrading your mirror, the white connectors will mate with the male connector on the LED module that mounts on the existing door mirror frame. The wires are run inside the mirror frame and out of the mirror through the existing metal conduit.
The small silver terminals then slide into the connector already on the mirror, allowing the pins in the door connector to mate with the now upgraded mirror connector.
This harness allows for easy conversion of the stock mirrors to STI mirrors on the 2015+ WRX.
Detail of Sumitomo connectors that mate with the LED module:
2015 WRX BASE, PREMIUM, and LIMITED
2016 WRX PREMIUM and LIMITED w/o Navigation
(LIMITED trim with Navigation comes w/ mirror-integrated turns)
2010-2014 WRX/STI (Note, you must use the R harness on the Left, and the L harness on the right - See Mirror Mod page for details)
This harness includes the assembled wiring and connectors you need to execute a plug and play installation of the turn signals integrated into the 2015+ STI and 2016+ WRX Limited from the factory into cars not so equipped, such as the 2015 WRX and 2012+ Impreza. Many thanks to NASIOC user Power6 for having made these in the past and teaching me how to make them for future Subaru owners.
