How to Install a Harley Rocker ECM
The FXCW Rocker delivers, according to the Harley-Davidson Motor Company, "custom-chopper style with Harley-Davidson quality and innovation, with features like the tire-hugging Rockertail rear section." Unfortunately, unless you build your custom chopper yourself, sometimes style and innovation conflict with functionality. For example, it might seem like a simple job to install a new Electronic Control Module. But before he can install a new ECM, the owner must first wrestle the innovative Rockertail rear into submission. There are a few steps that will help you access the Rockers electronic caddy and install an ECM.

Lift the rear of the Rocker seat and pull up and back. Remove the two exposed Allen bolts just behind the gas tank with an Allen wrench. Remove the seat.
2Remove the four Torx bolts, two on each side of the bike, that secure the seat support assembly to the motorcycle chassis with a socket wrench and Torx socket. Remove the seat support assembly.
3Loosen the four hex head bolts that secure the black, plastic, guard under the seat assembly with a socket wrench and hex socket. Remove the guard.
4Disconnect the rear wiring harness connector halves.
5Remove the lower fender mounting bolts and washers with a socket wrench and Torx socket. Remove the upper fender mounting screws and washers with a Torx socket. Remove the rear fender.
6Remove the harness clipped to the right side of the electrical compartment splash guard just forward of the rear wheel. Remove the two hex head bolts and washers that secure the splash guard to the chassis. Remove the splash guard.
7Remove the two bolts that secure the electrical compartment cover to the electrical compartment body with an open end wrench. Locate the ECM next to a fuse marked "40."
8Unplug the ECM from its pigtail connection to the wiring harness. Remove the ECM and install the new ECM.
9Reinstall the electrical compartment cover, the splash guard and the rear fender. Reconnect the rear wiring harness connector halves. Reinstall the seat support assembly guard, the seat support assembly and the seat.

How to Remove the ECM From My Harleys Electrical Panel
Harley-Davidson refers to the electrical control module (ECM) as being plugged into the "electrical caddy." The location of the electrical caddy, however, varies according to motorcycle model. On V-Rods and Buells, the caddy is under the rear seat; Rockers and Night Trains require you to remove the rear fender to access the ECM. On most Harleys, the caddy is on the right side of the motorcycle, approximately under the seat. Check your owners manual if you are unsure where the electrical caddy is on your motorcycle. This procedure works for all Harley Dynas and Wide Glides.

Loosen and remove the bolt and washer on the rear tab of the motorcycle seat using an Allen wrench. Remove the seat by pulling up and back.
2Disconnect the negative (black) battery terminal using a box wrench.
3Remove the electrical caddy cover by firmly grasping both sides and pulling outward.
4Insert a small screwdriver into the slot under each relay/fuse panel to disengage it. Insert two small screwdrivers into the slots on each side of the main fuse. Depress the tabs of the main fuse connector with the screwdrivers and remove the main fuse.
5Depress the tab that secures the Turn Signal Module/Turn Signal Security Module (TSM/TSSM). Pull the TSM/TSSM from the electrical caddy and disconnect.
