I know its too late but in case anyone else installs these it isn't necessary to remove the tank.
Disconnct the fuel line with the quick disconnect then just remove the mount bolt under the seat and rest the aft tank flange on a small piece of 2x4. Then find the harness sleeve inside the fairing on the left side (of the bike if you were seated in riding position) and remove the wire tie holding the end of the loom closed.
Remove the pins from the power connector and insert a wire coat hanger from the inner fairing inside the wire loom under the tank. Put a small "u" in the end and tape the 2 power wires to the hanger and gently pull them through the loom and into the fairing then reinsert the pins.
No mess and less than 10 minutes for this step and the wires are safely secured in the factory loom.
Hope this helps the next fellow?
