Bob has an FL ready to install a Power Commander. Watch as he snakes the harness through the battery tray compartment and through the frame to the ECM connector on this model. He re-installs the loose backing plates and installs the Power Commander to the ECM with a little dielectric grease. He takes his time to make sure all components are back in their place. The factory did not smash things together so neither should we. He uses tie wraps to keep everything in place. The Power Commander is easily mapped with a computer for the exhaust / air intake set-up on the motorcycle and makes it easy to remap till it’s properly dialed in.
