OBD-II port (how to run 2 gauges on one port)

Thanks for the link CFG83, but like you stated probably not worth it. I'll just figure something else out.

More about CAN, it began being introduced in 2003/2004 and it's really not an OBD-II replacement from my new understanding it's really just a hub/router. The ECU sends a message to CAN then CAN assigns priority and sends it to the required assembly and OBD-II just regulates it. I understood it mainly because of my limited computer networking knowledge. But apparently the OBD naming convention will be kept, so I guess in the future we will have OBD-III to look forward to.

How about the SGII's second port?
I remember reading someplace about daisy chaining 2 SGII's for more functionality.
No Idea if that helps or not.

I can try and chain 2 SGII's with a Ethernet cable if that helps any, but that's the only OBDII Device that I have so . . . ..

krousdb is doing this in his Prius (2 SGII's) daisy chained.

That would be a little less clean, but I'll look for a cat5 male to OBD-II female and try that out.
