• Please check your connector matches the header in the listed photo before purchasing. 
• This ECU works for manual transmissions only.  
• Air temp sensor highly recommended.
• Most factory features are supported.

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.
