04.5 sportsman 500 Speedo bypass? Tcm?

Hey guys I bought this Sportsman from a salvage yard. The speedo worked for a while. Now it has completely quit. Is there a way that I can by pass this thing and make everything else work with out it? I don’t need the a speedo. Does this atv have a tcm? I’m having some ongoing electrical gremlins and would like to take these two potential problems out of the way.
