3. Remove the grounding screw with a 10mm head just below the shifter base and add the Optimizer’s ground eyelet to the existing group of wires.  Make sure all connections are back on the screw and install it back into the frame of the machine.(See Figure #2)

4. Using the supplied zip ties secure the Optimizer’s wiring harness to the frame. Take care to double check the routing of the Optimizer harness is away from any hot or moving parts such as the shift linkage.

5. With the supplied velcro patch mount the Optimizer under the seat just behind the fuse box.(See Figure #3)

6. Turn the ignition switch on, the Optimizer should power up for a short time then shut off.  Optimizer power up will be indicated by a sequence of flashing lights on the box.  If the Optimizer does not power up check that the Optimizer is properly grounded and plug connections are secure.  While the engine is running the Optimizer's lights should remain on and will change based on load and throttle position.

7. Reinstall all parts in the reverse order from where they were removed.  Check clearances and ensure no wires or parts interfere.

NOTE: If you ride in deep water or mud and the Optimizer will be submerged when mounted under the seat alternate mounting is recommended.  The Optimizer is water resistant but is not designed for full immersion.

NOTEBase tuning for the Optimizer is pre programmed.  This tuning was determined with our HMF exhaust being the only modification.  Varying outside conditions as well as other modifications to the machine may require some fine tuning.  Test drive the machine prior to changing the base settings. Installation and tuning is the responsibility of the end user.  HMF will not be held responsible for property damage caused by improper installation and/or tuning.
