From the schematics, the blue/green wire carrying the VSS signal comes from pin 42 on the ZFE module. So even if the blue/green wire is deleted from the harness on the 2010 and later bikes, the VSS signal might still appear on pin 42 of the ZFE controller.
THANKS! And great idea...we'll try to chase it down because after we install one on Bohn's 2006...we will attempt to do same on Jay's 2011 GSA.
