For any of you who are fans of Mustang seats....but held back because they did not have OEM controlling the adjustment for heat....now they obviously figured it out and it controls heat via Honda OEM controls! I just placed my order about a two week turn around. The drivers/passenger seat now comes with the backrest as standard, not as an accessory. I have tech department checking if you have to purchase the Mustang passenger backrest because the information they provide is that you have to have both the driver and passenger backrest wired for the system to work. They didn't specify if the Honda OEM passenger backrest would work. I prefer the OEM backrest after not liking the look of the Mustang passenger backrest. I should get an answer tomorrow. Nice not seeing the toggle switch on the side of the driver seat. I have no affiliation with Mustang seats, I just love their product as I had one on my 2012 GL1832, interestingly I was able to get my Utopia backrest to fit that Mustang seat. Hopefully, I can do it with this one as well. Ride Safe and my miles and smiles should be reflected on my new Mustang seat because the OEM could not even with the Wingsoft makeover it did not do anything for my posterior blues.
