The posts above this one, these guys are all right for the most part. These switches are weird in that they have a lot of options. Generally you can plug just about anything into that left side cover or under the seat ACC connections and the ECM will know what to do. As far as the actual switches go, you just need to pay attention as to whether you're wanting to use an on-off switch or a momentary switch. The right side switch assembly are CVO and you won't find it at a dealer, they'll say they don't even show it in the system - that part No is 71400033 SWITCH PAK, ILLUMINATED, LOCK/UNLOCK and you can find it at Boardtracker; it has the lock-unlock momentary switches, and one blank (that you can change, if you want). The left side I am NOT sure can be changed to a momentary button(s) but mostly we see them used for lighting; the furthest left button is Aux lights, (the only active one it comes with, and if you use if for Aux lights, you want the harness for them that plugs into the turn signal harness, no left side cover involved; and you want to have the dealer flash the ECM so you can control them independent of the high beam) middle one is Fogs (or something else, goes to the left side cover) and the right ACC is an accessory button for whatever you want, that can be flexible as well. The left switch is part no. 69200172 SWITCH ASY, DASHPANEL, MTND, FOG and the dealer can get you that one (or get both at Boardtracker) and you can find the buttons if you want (dealer again, or you guessed it, Boardtracker) to change them (cosmetic, or functional, but again, I don't know if you can change them to momentary [itd be nice if we can, but that pak does specify MTND, "Maintained", or, on/off]). It only comes with ONE active button and the other 2 are blanks that you can change out to active ones (the $13 thing you read about in an above post) all this I learned about on my 2014 SG. Both those paks are $80-$100, I forget.
And that's about all I got... I'd be interested to know if we can modify the button action to off-on to momentary on that with a button change, myself. I have both paks, I guess I could try and swap the buttons and see if they work... didn't think of that til just now..
