Hi, I didn't notice this request. There is a pdf Service Communication on the Polarisdealers.com website that explains the kit and the components if you search for PV-51895. I bought the CAN interface and made up the cables. The cable drawings are on here and the ends I bought from Mouser.
What are you hoping to do once you have the kit or parts? I've only used mine to check the batteries.
Data can be read off the mini usb stick using the Victory software etc.
