    I google "Harley Davidson P0263" and this is defined as "rear injector open/low EFI". I am sure someone here will chime in to help you.

    Some (myself included) had problems with the wire harness being a little snug, with all the vibrating the metal wire inside would break and create an open. Like putting your fingers together and pulling apart and again creates an intermittent type problem.

    Try wiggling the wires to the rear injector to see if you can fix/create the problem.

    Is there any type of tuner on the bike? Is wire bail on connector securely
    attached to the fuel injector? Check connections.
    Perform a WIGGLE TEST to check for intermittent s. Intermittent s present?
    P0261 Front injector open/low
    P0263 Rear injector open/low
    ECM fuse and system relay failures or wiring harness problems
    will cause 12 volt power to be lost to both injectors, ignition
    coils and fuel pump.

    You should be able to buy a new terminal for the wire at your local HD shop. Just re-crimp and install. Add a little wire if need be.
