Brilliant - thanks Mark.

My OVMS has been offline for a few weeks due to my 12V issue, and then being away for work... I'm due to get it replaced today (2nd attempt.. let's see if the dealer actually has a suitable battery this time!) at which point I can get the OVMS back in to experiment.

I'm pretty sure the EV bus is going to be a lot more useful to work with, especially in terms of battery/charging data so I'll be ordering a cable the instant I can! Thanks so much for getting the cable specced.

I've ordered a bunch of cables suitable for CAR and EV can buses of Nissan Leaf. Pinout is:

Pinout B

J1962-M DB9-F Signal
4 3 Chassis/Power GND
6 5 CAN-H (alternate CAN)

14 4 CAN-L (alternate CAN)
13 7 CAN-H (primary CAN)
12 2 CAN-L (primary CAN)

16 9 +12V Vehicle Power

J1962 end should be MALE plug with right angle cable. DB9 end should be FEMALE.

Both ends should be enclosed in shells, and cable should be 1metre in length.

The wiring brings J1962-M pins 13 and 12 (EV can bus) through to our standard OVMS v2 can bus pins. It also brings the normal CAR can bus through on DB9-F pins 5 and 4 (for future use on any dual-can enabled OVMS module, or easy re-wiring at the DB9 end).

Cable itself as per our standard naming:

For simplicity, I'll ask Fasttech to handle logistics for these, as usual.

Regards, Mark.
