OVMS vehicle cables for connection to can-bus equipped OBDII vehicles are now available from our FastTech logistics partner. You can find them here:

OVMS OBDII Cable @FastTech

This cable connects the OVMS module to the vehicle CAN bus, via the industry standard OBDII socket. It is 1 metre in length, and uses a right-angle OBDII plug (J1962-M) to help with cable management and routing.

The cable is intended to be used in Renault Twizy, Chevy Volt, Opel/Vauxhall Ampera, and other cars using OBDII connectors.

I just complemented my Roadster with a Volt (replacing a gas sedan).
Great to see you guys also supporting other vehicles.

How to get started with Chevy Volt?

Hi Folks,
I received this cable and would like to get started on my Chevy Volt.
I have a v2 car module that is working fine in my Tesla Roadster, using the firmware it came with.
What do I need to do to try this in the Volt?
Can it simply be plugged in using the OBD2 cable, or do I need to build and install a Volt specific development firmware?
By all means send me a link where to RTFM.
Regards, Richard
