I'm trying to install a used gauge/display and I tried to plug it into my 02 polaris virage... And the gauges work but when I plug it in... It won't allow my jetski to start... I plug back in my old mfd and it starts right up. Does anyone have an ideas??

Here is a link to the part I am trying to install
