—Testing—
1. Connect the tester to
the vehicle
• DLC Connection
• Direct Connection
2. Hang the FMU vertically from
the vehicle's hood
3. Connect the MCU to power
• 12V power adapter
• Battery hookup
4. Insert the drain hose into an
approved fuel container
(min. 16 oz.)
IMPORTANT
If the engine is hot, or after cleaning the injectors, make sure you allow for
a cool down period before you begin testing. A hot soaked engine condition
may affect the test results.

Connector
Used with most vehicles, this connection controls the injectors and the fuel
pump through the DLC. Use this hookup when using the vehicle's diagnostic
link for injector control. This connection does not require the use of the
injector harness.
1. Connect the 10' serial cable to the MCU and the DLC adapter.
2. Connect the DLC adapter to the vehicle's OBDII connector.
3. Connect the Fuel Schrader Connector to the vehicle's fuel rail at the fuel
test port.
This connection directly controls the injectors from the MCU. The fuel pump is
controlled through the DLC connector. Use this hookup when testing vehicles
that do not support diagnostic link injector control. You must the use the
injector harness with this connection. However, do not connect the injector
harness until instructed to by AFIT.
1. Connect the 10' serial cable to the MCU and the DLC adapter.
2. Connect the DLC adapter to the vehicle's OBDII connector.
3. Connect the Fuel Schrader Connector to the vehicle's fuel rail at the fuel
test port.
4. Connect the injector harness (or J-Cable adapter and cable, depending
on vehicle) to the MCU and the vehicle's injectors. IMPORTANT! Do not
perform this step until instructed to by AFIT (the unit will prompt for the
correct injector harness or J-Cable adapter and cable).
Note: To correctly match test results to the injector, always use the injector
locator function on a direct connection hookup.
When using the optional kits for older GM and other manufacturers'
vehicles, direct hookup to the fuel pump circuit may be required. See the
AFIT User Guide for details.
