I want to add heated grips to my ‘06 IIIA GL1800. I have Raynaud’s and my Gerbings don’t seem to always keep up. Short rides are manageable. But, on longer rides, there can be a significant loss in dexterity. Being a model IIIA, it didn’t come with heated grips. Reading previous posts, I was hoping that I could just add the OEM grips since they were designed for the bike and it would just be plug and play. That will work only if the IIIA wiring harness has the wiring and connectors for the grips and controller. Or is it different than all the other models that included the heated grips and seat from the factory?
