After some feeling around, I found there is the +12v plugin coming off the main TOP plugin that is in center of sled with hood removed. Just feel around behind there where top of frame all comes together near top of steering post. Two plugins are there, but way in behind so you need to feel for them, The smaller one is the 12v plug which is same as many BRP accessories.
RED ARROWS in pic show the short wire with brp accessory plugin, red circle in 2nd pic shows plugin.
I also decided to remove the gas tank cowl/shroud, since I have much wiring/electronics to hookup and this allows for easier access to the iTC shiny wire plugin that needs to be unplugged, its under and behind the tank shroud.
-retaining screw(under gas cap)
-Two large torx bolts- one each side
-seat off to remove the gas tank cowl
-Unplug DESS plugin and ECO switch plugin(underneath cowl)
TIP: Put gas cap back on so you dont drop something in.
