CanBus
I got an OBD2 extension cable with 90 degree ends to make a low profile connection. I cut the cable in half. (Photo!) Now I have a connector with a 12" cable ready to use.
Termination
I don't need termination as long as my cable is less than 0.5m long. (It was 18" but I snipped it down to be on the safe side.)
Signals
Signals that matter to me, and the wire colors:
5 signal ground -- orange
6 CANH -- Black
14 CANL -- Green
16 12V always on -- Brown
MCP2515

I intend trying this one first because it's got a more commonly used chip on it.
