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.   Some newer transmissions do not have the built-in vehicle speed sensor that the older chassis’ ECU and gauge cluster need to read speed.
