I am looking for some instructions on how to install the plug n play turn signal kit for a 2021 800ex.  The kit comes with a switch, flasher, both back taillights (that need to be replaced) and front turn signal add ons.  I can't find any instructions on what needs to be taken apart, mostly with the rear lights (it appears that maybe I need to take out a bunch of plastic rivots to gain access to those??), and I was told by the dealership that there is a connector for the switch in the dash already, just needs the hole punched out for switch and it will plug in.  Any help on this will be appreciated.
