Not sure which controller is right for you? Check out our DCCD Controller Buying Guide.


DCCDPro installations for your Subaru made simple! Hunting under the dash for the right wire to tap or cobbling mismatched plugs together are a thing of the past. Using high quality materials and a modular design, iWire has created a virtually plug and play for the DCCDPro Manual Controller.  Just insert our adapters, tap one wire, and you're done!




Note: If you have a pre 2007 chassis and a post 2008 transmission you will need a VSS Pro to get the speed sensor working. VSSPro Info Here.


Note: Only for Manual Cars. This is not an auto to manual conversion solution!
