I just installed the Roadstercycle super harness on my 2006 FJR1300 AE. Before installation I was measuring 13.0 volts at idle - 1050 rpm. After installation 13.8 volts. It was a lot of work installing the harness because it’s a little too short. The location of the shortstop device also makes it difficult. I attached the red positive lead to the starter solenoid to shorten the distance. If the harness was 6-12 inches longer, and the positive lead from the shortstop was 12 inches longer, the installation would be a snap. Then you could put the shortstop under the tank or under the right upper fairing, and wire it to the battery.
