WRX11X G4X PlugIn ECUs offer the latest in engine management technology, designed to easily maximize the potential from your car.  
This ECU fits inside the factory OEM enclosure. Installation is a breeze, with no alteration of the factory wiring loom required for the models listed below. 

Designed for the WRX & WRX STI V11 EJ20/EJ25 Turbo (GR/GV/GH/GE chassis, MY2007-2011, Denso ECU from factory). All factory functions including DCCD, hill start assist, SI drive, cruise control, cam control & ABS supported. 

Note: Some North American models may have a Hitachi ECU which is not supported.

Supported Models as of Sept 2023:
• 2007-2011 WRX and WRX STI with GR/GV/GH/GE chassis codes, for JDM/AUDM/SADM/EURO
markets, with turbocharged EJ20 or EJ25 engines.
• 2008-2010 USDM models which have the common international Denso ECU pinout*
• 2015-2021 WRX STI with VAB/VAF chassis codes, for JDM/AUDM/SADM/EURO markets, with
turbocharged EJ20 or EJ25 engines.
Partially supported Models as of Sept 2023:
• 2012-2014 WRX and WRX STI with GR/GV/GH/GE chassis codes, for JDM/AUDM/SADM/EURO
markets, with turbocharged EJ20 or EJ25 engines.
Please note - testing of these models has found the Check Engine light remains illuminated due to a CAN
bus change. It appears everything else works correctly, but it has not been thoroughly tested in all regions.
We are aiming to be able to fully support these models in the future.
Unsupported Models as of Sept 2023:
• 2011 onwards USDM WRX or WRX STI. These models have a significantly different pinout that is not
compatible with the Link WRX11X plug-in ECU.
• 2015 onwards VAG non- STI models which have the FA direct injected engine.
Important Notes:
• This ECU works for manual transmissions only.
• Please check your connector matches the header in the photo on the WRX11X Product Page before
purchasing.
• For USDM cars, please check pinout matches prior to purchasing. See * note below.
• Most factory functions including DCCD, hill start assist, SI drive, cruise control, cam control, MFD, trip
computer/fuel consumption gauge, ABS & DSC supported.
• The immobiliser lamp may remain illuminated on some key start models which have the factory
immobiliser option. The only way to solve this is to remove the bulb.
• An Air Temp Sensor is highly recommended for models that don’t have a factory one.
• Check the features tab for I/O expansion options.

Note: This Plug-in features a new 4 pin powered CAN connector and cannot use the old CANPCB cable for CAN connection.  Use the CANJST4 (Link PN 101-0198) cable for connecting CAN devices.  This new 4 pin port and cable provide not only the CAN connection, but also a protected 12V power supply and ground for powering the CAN devices.  The power supply is protected by a self-resetting fuse rated at 3A continuous.

A little snug on the thighs
Size: Medium, Color: Multicoloured G (5-pack)
Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Functional + Sexy
Size: Small, Color: Multicoloured E-(5-pack), Size: Small, Color: Multicoloured E-(5-pack)
Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.
