AK knows his stuff... and has a new 850 in his stable, I believe (I do not)... so I'd defer to his post... and assume that Polaris has changed out to an actual sealed connector on the warmer. The past Metri-Pack 150 Unsealed connectors were less than Ideal... and although the Weather Pack connectors are bulky... they seal well and are robust... they are very easy to source...even NAPA has them... the pins are easy to remove and connectors are easy to assemble.
Just make sure you use the seals that are small enough for the wire on the heaters.
PN 2414273, the GRIP HEATER, LO/HI, ALUMINUM is UNIQUE to 2019 sleds... so... there you go... I stand corrected and it seems you have purchased the correct connector.
Since you can re-use the connector housings and seals from the original heaters... You would only need the tool (Oreilly/NAPA etc) and some new pins, which you can get at NAPA etc (even amazon). If you dont want to cut off the pins from the old heaters... you can buy new seals easily too (probably the purple ones for that gauge of wire)
