[Ovmsdev] Quick update

Nigel,

No order yet. I'm waiting for the factory to finish specifying the cable (they are pedantic that way, and require a signed-off engineering diagram). It will be at least a few weeks before we can get the EV-bus cables.

I did try modifying one of our existing cables, but it was a bit of a mess. Being factory made, they are sealed plastic and not easy to take apart at all. It would probably be easier to wire one up from scratch.

Regards, Mark.

Since this is just experimentation, and I use a splitter the L/R direction doesn't matter to me. If not are these cables easy to specify as one-offs? where would one get one from?
