There is a bullet type connector in that area that you unplug for running ethanol gas. That is what your dealer is referring to. It richens the fuel mixture by 5% which may be enough to stop the detonation. If you aren't running known fresh premium non ethanol fuel you should unplug those wires. Worst thing that can happen is that you will burn a bit more fuel. As far as I know when you unplug the wires it does not retard timing. If your sled goes into detonation mode then the ECU retards timing.
I'm not exactly sure when Polaris started putting that feature in their sleds. I thought it was 2009 as I'm pretty sure the early CFI sleds did not have the bullet connectors. Here is a video that shows location and procedure.https://www.youtube.com/watch?v=n1TwzsRRrB8
The older I get the better I was; In fact now that I think about it I am a legend.
