Welcome to PRC!
If the buss bar you are referring to is the one with 3 terminals (probably under your hood), it's probably not wired. Polaris used to wire all three terminals on the older models, but lately, they only wire one, the "keyed hot" terminal. Not sure if this true on the new 570's or not. Easy to test with a meter or test light. If the other two terminals are not wired, you can order a harness from a dealer or make one up yourself.
P.S. If your dealer won't help you out with this type of problem, he's a jerk - I would tell him to pack sand then find another dealer.
