7.0 HARNESS INSTALLATION
.
7.1 Lay the harness onto the lower intake manifold
being careful to position it according
to the layout
of the engine. Fuel Injectors #1, 2, 3, and 4 are
on the right (Passenger, USA) side of the engine
compartment. You may attach the fuel injector
connectors at this time.
7.2 Attach the connector
for the TFI
Module located on the distributor.
(Page 6, Connector #15)
7.3 Attach the connector for the ACT
Sensor. This is usually located at
the front of the lower intake manifold
in the top of the #5 intake runner.
(Page 6, Connector #13)
7.4 Attach the connector for the ECT Sensor. This is generally located on the right
side of the engine towards the front. (Page 6, Connector #11)
7.5 Route the leads for the Oxygen (O2) Sensors behind the engine towards the left
and right oxygen sensors being careful to insure that the harness will not lie
against any portion of the exhaust pipe. If the harness can freely touch any portion
of the exhaust pipes, it should be tied back using ‘zip-ties’ or another suitable
substitute. The connectors can be attached to the O2 sensors at this time.
(Page 6, Connector #21 and Connector #22)
7.6 Attach the connector to the BAP Sensor. (Page 6, Connector #20)
7.7 Route the wiring with the battery leads around the left (Driver, USA) side of the
engine compartment. DO NOT HOOK UP THE BATTERY AT THIS TIME! The
harness has been designed to mount the Coil in the fender well on this side. You
may attach the connector to the Coil at this time. (Page 6, Connector #16)
7.8 If you are using a Ford A/C compressor, you may attach the connector for it at this
time. The harness should have enough slack to route the lead under the
compressor and up to the connector. This will help keep it away from the fan belt.
