IQ3 Drag Dash Installation Manual

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.

Wire Connection:
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
Main connector Pin 26 = Green = Can Low
Adapter harnesses available
Although the consumer can terminate the mating Deutsch connector and connect to their ECU,
adapter harnesses are available to ease installation. Mating connector is not supplied with
dash, but is supplied with below adapter harnesses.

See included chart for list of available channels from each ECU. List may vary slightly as
interfaces are sometimes being updated with information from ECU manufacturer.
Once connections are made, the dash will have to be synced and programmed for the selected
ECU. See

sections for instructions on
programming.
