My cousin showed me a Polaris to ODBII adapter in eBay the other day. There are several different ones and they claim to allow you to connect the Polaris diagnostics connector to an ODBII code reader. Has anyone ever used one of these? I'm wondering what all it allows you to read, other than error codes, or is that it? If that's all you can do with it, it'd be pretty redundant since you can do that from the display. Just don't want to waste $30-40 for a gimmick.
