Thanks! Have the Garmin AMP mount, so I should be good to go. I'm assuming it'll mount directly to the stock glove box or extended? Is the a 12v source within the glove box?
I helped my buddy install the BRP Zumo kit on his Gen4, and we compared the normal Garmin AMP harness to the BRP harness. All BRP is doing is taking the Garmin harness, and adding a quick connect plug to the red/black 12V wires on the Garmin harness. That 12V plug is found on the left side of the sled, under the hood between the handelbar and headlight. It's to the left of where the speedometer would be, and if I recall correctly is just a grey 2-pin plug sitting there not connected to anything. BRP accessories like the 12V outlet, USB, etc. all connect to this plug. So all you have to do is tap into the wires using that plug, or if you really want to get fancy, you could get a cheap BRP accessory like the the 12V outlet (Part # 860201423) and cut the OEM plug off the end and connect it to the AMP harness.
It's worth pointing out this is not an always-hot 12V plug. It's only hot when the sled is running, even if you have electric start. So the GPS will turn on and off with the sled.
