Part unknown?

Anyone know what this is for? Just bought the 2010 sled and it was under the seat storage. Looks like a spare, I've seen it under the hood but have no idea what it is.
TIA.

Thats a resistor that plugs in and tells the engine management system what fuel you are running.
There should be info on it on one of the hood panels and you can also look up your owners manual on Polaris website and read more on it, see below

I signed up on that forum and asked for owners manual and it said none available for that sled? But I did have an owners manual already, downloaded from a site I don't remember, lol.
Do they go bad, just wondering why there was a spare under the seat compartment. This is my first Polaris sled, had 5 yamaha's and a couple of Doo's. Hope my experience with Polaris will be a good one.

The manuals are available to the general public at that link I posted above, no need to sign up for anything. Just click the drop downs and select your year and model. They have every model listed there back to 2000. Make sure you don't have the manual for the older carbureted widetrak version.
There are 2 separate resistor plugs depending on the fuel in those models, they are marked at the flat end Ethanol and non-Ethanol. Unless you know you have good quality non-ethanol fuel, I'd leave the ethanol plug in as its the richer "safer" tune.
They talk about each in the "Operation" section of the owners manual.

Not sure what I did wrong but the link worked tonight, tks

Also, the spare that was under the seat is written 10% ethanol. I'll check which plug is currentlly being used. tks
