S&S Cycle Universal EFI Wiring Harness For Delphi Style Modules - Manual (Page 2)

4. Route the ignition coil lead and connector to the ignition coil and
plug into the coil. The lead length was designed extra long to
facilitate various coil mounting locations. Loop back and wire tie
any excessive coil lead if necessary. See Picture 2.
5. Route the ECM connector to the ECM and plug into the connector.
The ECM lead length might be extra long for your application. Fold
back and wire tie the excess lead length if this is the case. Refer to
the below picture. If the harness is too short to reach the ECM, then
the ECM mounting location will need to be changed. See Picture
3.
6. Route the Crank Position Sensor lead in the most appropriate
manner to the Crank Position Sensor connector. Some factory
Harley Davidson sensors have very short lead lengths. If the S&S EFI
harness will not reach the sensor connector (when properly routed)
you will need to purchase a sensor with a longer lead length.
7. Find a suitable location and mount the fuse/system relay block. This
can be wire tied in place or a sheet metal bracket can be fabricated
as a mount.
8. If applicable, find a suitable location for mounting the Bank Angle
Sensor (Harley-Davidson® bank angle sensor H-D® #32495-9). The
mounting orientation of the BAS is very important for proper
operation. Refer to Figure 1, next page.
The S&S Universal EFI wiring harness (P/N 550-0264) was designed as
an easy solution for implementing electronic fuel injection for custom
bike builders, racers, and as a replacement sub-harness for 2002-2005
Harley Davidson FL models. It can also be used to simplify carbureted
to EFI conversion on just about any motorcycles using the HD® Delphi
style (36 pin) ECM or any aftermarket Delphi replacement ECM. Minor
modifications external to the harness assembly might be required for
certain applications. This harness is a standalone system designed
to control and run only the engine. It does not provide for lighting,
instrumentation, etc. Any modifications required to adapt this harness
to your particular application should be accomplished on the sub
harness side and not on the main harness. Modification to the main
harness without prior approval from S&S will void the warranty. Please
contact S&S tech support prior to installation if you have any questions
about this product or your application.

Installation
1. Begin by reviewing the harness layout & wiring diagrams in the
back of these instructions. Understanding what all the connectors
are used for and where they will go will be very beneficial in
completing the installation. Pay close attention to the routing and
location of the harness keeping the wiring away from extreme heat
sources or sharp edges. The complete engine should be installed
in the chassis and the fuel tank removed from the motorcycle. The
battery should be disconnected (if installed) prior to installation.
2. Lay harness on top of engine and connect the Throttle Position
Sensor (TPS), Manifold Absolute Pressure (MAP), Intake Air Temp
(IAT), Idle Air Control (IAC) and Engine Temp (ET) sensor connectors
to the correct sensor.
3. Connect the (labeled front or rear) fuel injector connectors to the
front and rear fuel injectors verifying the front/rear labeling is
correct.
