I have an Orion BMS that I pulled from my electric conversion that had about 200 miles on. It worked great before I took it out about 3 years ago.
It is the 60 cell model.
I have the OBD interface (CANdapter), coulomb counter, and a wiring harness. The CANdapter is amazing because you can create custom PIDs and view them with a wireless OBD tool on a tablet or phone.
The wires on my harness are extra long, but if necessary, Orion makes custom harnesses.

If there is any interest I'll post pics. I can ship to the US contiguous for free.
