Ford Harness Connections
J1939 Interface Information
A J1939 CAN input is required to provide engine information to the governor. The
Ford vehicle CAN Bus information needs to be interpreted. A J1939 Translator Module
with a harness to connect it to the ODB-II connector must be installed.
Note: The ODB-II connector and wiring is accessed under the dash.
There are two scenarios:
I. The J1939 Translator Module is installed as a component with governor kit
(no Seat Belt Monitoring System is installed).
Install the J1939 Translator Module and the ODB-II interconnecting harness
(provided with the governor kit). A 2-Pin connector is provided for the wires to
governor.
II. The J1939 Translator Module is installed as part of the NFPA1901 compliant
Seat Belt Monitoring and VDR System.
The Translator Module/ODB-II/VDR harness is under the driver side dash.
A T-cable (provided with the governor kit) needs to be installed at the 4-Pin
connector that is between the harness and the VDR.
Stationary Elevated Idle Control (SEIC) Interface Information
Note: Access wires for SEIC are located in cabin, tagged and bundled above
the parking brake pedal assembly behind datalink connector.
SEIC is used in two modes: stationary and split shaft. The governor provides a
variable RPM control to the Ford Power train Control Module (PCM) when all enabling
conditions are met. Refer to Figure 14 Ford TGA306/406 PCM Wiring.
SEIC Enablers: Parking brake applied; Foot off of service brake; Vehicle in
park; Foot off of accelerator pedal; Vehicle speed is 0 mph (stationary); Engine
at a stable base idle speed.
Note: Do not press the accelerator or service brake pedal when engaging the
re pump, this prevents the switch into SEIC (Stationary Elevated Idle
Control).
