2017 30kWh main harness connector pin diagram

[GregFordyce]

Pinout diagram for the motor main harness connector on a 2017 30kWh Leaf. It's a differnet connector than my 2015 Leaf and also appears to be the same as a ZE1 Leaf as per this post. I have used the same numbering system from that post because I couldn't find a Nissan diagram of the connector. All other pin numbers are as per Nissan.

Corrected CAN bus pins 2025-07-10

I found some errors in the CAN bus pins and have re-uploaded the corrected files above.

Thanks for mapping the pins for the main harness GregFordyce! I have a 2017 so I have updated my diagram, would be great if you could give it a look over.

I now have the ZombieVerter and have wired up my harness, so it's bench setup time soon

Questions:

- Given 36 & 37 and 45 & 46 go to the same pins, I'm thinking i don't need to run the canbus to both?
- Both stock Leaf charger sockets are still connected to the main stack, I'm unsure about where pins 35 &44 go? I watched Damian's video, and he talks to the wires going to the charging socket but I can't seem to find the documentation about precisely where those wires attach?

The CAN for Inverter and PDM are joined in the engine bay side harness, so you need to connect CAN H and CAN L for both on either side of the connector. Up to your preference, whichever way you want to do it

The 35 and 44 go to the AC charge port

I connected to both sets of canbus wires but either set should be fine.
