I'm presuming that you connect the OVMS to the OBD-II connector with a
cable made for the purpose.  Do the desired CAN busses appear on the
OBD-II connector?  If not, you'll need to find some other connectors
(or wires) where you can pick them up.  And then the CAN bus pins on
the car need to be wired to the right pins on the OVMS where it
expects to see CAN busses (up to 3).

Other than the cable(s), other devices shouldn't be required.
