Installed the OEM heated seat and heated grips today. The heated seat comes with the switch that installs in the dash. All the connectors are on the bike's wire harness, so everything is plug and play, at least they are on my 2013. Very easy install, took about 20 minutes. The heated grips are a little more difficult to install but there were no surprises. I did discover there are two other unused electrical connectors on the bike's wire harness in the same area as was found the connector the heated grips plug into. What these connectors would be used for I have no idea. I tested out the heated grips and they get very hot. I haven't had a chance to try the heated seat yet, it is 108 degrees today in Phoenix.
