John, The older packs have a different connector on the outside, but on the inside of the pack it is the same (not all wiring - the battery sense wiring *is* pinned out differently, even though the plugs are the same! Beware!)
Luckily the pins are the same signals on both: CAN bus, ground, +12V and the 3 relay coils (precharge and 2 main contactors) I can send you the service docs or you can simply use the picture that I uploaded to the US Electricar Yahoo group which should be open for public viewing, since we are converting the trucks to run with Leaf packs: https://groups.yahoo.com/neo/groups/uselectricar/photos/albums/184164318 3/lightbox/1587293210 The pin 4 is +12V from ignition key switch, pin 5 is permanent +12V battery connection and pin 21 is +12V during charging. Pins 6,7 and 8 are all ground and are shorted together inside the BMS computer.
