AEM CD-7/CD-7L Plug & Play Adapter Harness for OBDII CAN Bus

AEM's OBDII CAN Plug & Play Adapter Harness make CD Dashes the perfect racing displays for track day enthusiasts who want to be able to see engine and vehicle data but are still running a factory ECU. This is especially true when a CD-5 Carbon or CD-7 Digital Dash and OBDII CAN PNP Adapter Harness are combined with the Vehicle Dynamics Module to add GPS, 3-axis accelerometer and 3-axis gyroscope for track mapping and lap times, and critical vehicle dynamics data including G-loads, roll, pitch and yaw. And for CD Dash owners with CAN OBD-II who are already using the dash and receiving channels from a data logger or other CAN-enabled device, you can now add additional channels through the OBD connection with no additional wiring!
