Connections
Connect all engine/vehicle-side connectors before connecting the harness to the ECM. All engine/vehicle-side connectors are
functionally labeled, consult a service manual if necessary to determine connection locations (see following service manual
information).
Note: It may be easier to install the harness on the engine before installing the engine into the vehicle.
The harness includes a fuse/relay center containing all required fuses and relays, and also a 12-way bulkhead connector (with
sealed mating connector) which contains outputs that may be useful to the user (see 'Bulkhead Connector Outputs' section
below). The fuse/relay center should be mounted as high in the engine compartment as possible to avoid unnecessary splash
and road debris. Likewise, keep the 12-way bulkhead connector and diagnostic link connector (both connect from the fuse/relay
center) as high and protected as possible.
The 3 ECM connectors are indexed to connect only in the correct locations. Install by pressing down firmly until the connector is
seated, then pull the top slider bar down until it snaps and locks into place. The bar should slide easily and will not move unless
the connector is seated properly, do not use excessive force.
Attach the harness ground eyelets (3 total) to the engine block using the bolts provided, ensuring the connections are clean and
secure, and attach the fuel pump wires from the FPPM to the power and ground of the pump. It is acceptable to use one bolt to
attach 1 or more ground eyelets.
Make sure all intended engine and vehicle side connections have been made before proceeding to connect power.
