OBDII and EFI Interface:
The IQ3 Drag Dash has a CAN interface module built directly into the circuitry from the factory.
This interface is used to convert the CAN bus data stream found in most new vehicles, as well as
some popular aftermarket ECUs into CAN bus data that is compatible with the IQ3 Drag Dash.
Data from this interface is then available to display data from the ECU’s sensory array onto the
IQ3 Drag Dash.

There are two (2) wires found in the rear main connector used for the OBD II and EFI interface
connections.
A two (2) pin Deutsch connector is connected to the following wires:
Main connector Pin 17 = Yellow = Can High
