Jumpstart Your DCCD Install
To get the DCCD functionality working, check out our DCCD Controllers with wiring kits which include this adapter. This is a great feature that improves drivability of the car and performance of the transmission. If you already have a DCCD Controller simply run the Red wire (power) and White + Black wires (DCCD controls) provided in your kit to your controller. 

NOTE: OEM DCCD Controllers will not work outside of the STi they came from. More about this can be found here.
