DFIV Wiring Diagram
CAUTION
Disconnect the batteries before installation.
NOTE: If the vehicle does not have Cruise Control, remove the green and blue wire
from the install and discard.
Remove the lower section of the drivers side dash, under the steering column, and
mount the DFIV module to the structural brace. Connect the black wire from the DFIV
module to a good ground.
Locate one of the ignition switched red/black tracer wires under the steering column
(one is 10/12ga and the other is 14/16ga) and connect an appropriate Posi-Tap
connector to it (green for 10/12ga and black for the 14/16ga wire). Connect the fused
red wire from the toggle switch to this Posi-Tap and mount the switch in a convenient
spot on the dash.
Locate the Throttle Position Sensor (TPS) at the throttle pedal. Use a Posi-Tap
connector to attach the yellow wire from the DFIV module to the red wire w/gray tracer
wire (1994-1997 trucks) to the TPS.
Ensure the green wire is connected to the 'COM' terminal of the DFIV module, the
blue wire is connected to the 'FORD' terminal of the DFIV module, and the pink wire
is connected to the 'BRAKE' terminal of the DFIV module. Also check to ensure all
other wires at the DFIV module are secure.
