Ok, that might work, thanks.
However, I already have the TDC-S and OBD connector shells and pins.
I also want to make several for friends with just CAN3 and Power.
I am thinking of using:
1. individual wires, stranded for flexability,
2. wires about 6 inches long so the dongle can be hidden above the cubby,
3. use the largest diameter wire that the pins will properly crimp to, for strength.
4. use the wires in twisted pairs, like one black for Ground and for each CAN-Low,
5. and then other wire of the pair some other color, like red for the Power, and ...
6. four other colors for each CAN-High (or maybe one color if all the wires are fully visible from pin to pin).
I want it easy to identify wiring correctness before plugging in the pins to the connectors,
and easy to check the adapter's wiring visually, after assembly, before using it.
Then ... the basic TM-Spy adapter wiring would be like this:
1. Power to pin OBD 16 and Ground to OBD pin 4.
2. CAN3 (Powertrain) to the standard OBD pins 6 and 14 for the dongle (the LEAF's CAR-CAN bus),
And the additional three CAN buses for full logging ... what do you think?
3. CAN? (Chassis) to the LEAF's EV-CAN bus pins, ? and ?,
4. CAN? (Body) to the LEAF's AV-CAN bus pins, ? and ?,
5. CAN? (Body Test) to the CAN pins used on the Tesla OBD, pins 1 and 9.
At the moment, I have forgotten the (?) values.
