INSTALLATION
To protect against shock and accidental start-up of the engine, disconnect the negative battery cable. Inadequate observation of safety precautions
could result in serious injury or death.
1- Disconnect the negative battery cable, and relocate or insulate the cable away from the battery.
2- Remove the right side cover (Touring models) or seat (Dyna and Softail® models) to gain access to the ECM.
a- If installing on a Dyna, also remove the left side cover and the electrical caddy.
3- Depress the tabs on the side of the ECM connector and remove the clear retainer. Remove the zip tie and open the gray ECM connector strain
relief by releasing the three tabs.
4- Remove the following wires from the ECM connector by using a small screwdriver to gently lift the retaining tabs while pulling on the wire from
the back side of the connector. Wire colors may vary, so check that you are removing wire from the proper position.
Position 3 - Pink – Tachometer (may not be present on some models)
Position 13 - White/Black - Switched Ignition Power
Position 19 – Green/Gray – Rear Injector
Position 21 - White/Yellow – Front Injector
Position 24 - Gray/Violet – Throttle Position Input
5- Insert the wires removed in step 4 into the supplied six position Deutsch® connector per Table 1.
6- Insert the supplied orange wedge lock into the Deutsch connector.
7- Find a suitable location to mount the EZFI-C module. On Touring models, the EZFI-C can be piggybacked on top of the stock ECM. On Dyna
models, the EZFI-C can be located in the space to the right of the electrical caddy with the wires routed through the caddy. Use a zip tie or
Velcro® to secure the EZFI-C.
8- Plug the Deutsch connector assembled in step 6 into the EZFI-C’s mating Deutsch connector. Verify the wire colors across the six pin Deutsch
connector. They should line up per Table 2.
