Separating some of the BMS wiring loom to reach the three separate boxes without needing extension wiring. Considering how we want the battery boxes to be completely modular, I still need to consider extension wiring plugs for quick disconnect.

You'll notice the snout attached to the box is upside down. It will be right side up when installed since the door will be facing down. Zooming in you can see the + and - marks just above the orange plug. The Resolve-EV controller wiring will plug into the round black plug. The reddish connector originally plugged into the harness that went through the floor of the Leaf. I guess that just stays unconnected, although there are a couple wires that plug into the hardware within the box connected to this plug.

Regarding wiring, I didn’t use the 3rd (square one) of the 3 connectors on the outside of the battery that supplied the car’s hvac stuff. I just cut that section including the socket off the aluminium metal work. So any wiring that connected to that on the inside of the battery was left out in my build.
It’s possible in the future I may get back to wanting heating, but I’ll cross that bridge when I get to it. -

BMS with all the harnesses attached. Not sure if all these connections are necessary for our build but we're going with it until we hear otherwise. Anyone want to comment on what's necessary and not? I'm not sure how to invoke the "@isak" link for his response. It would be great if someone could help me with that.
@leshall89 All the BMS connectors are necessary except the ones going to the relay that controls the resistive heaters that sit on the cells (not all leaf packs come with resistive heaters). It's the cables that go from the BMS to a rectangular black box. Temperature sensor cables connector and the 12V and CAN connector and the rest of the balancing wires are all needed for the BMS to not throw a fit

It’s not normal to get N206c error message on the display. Try working out what that means.

@isak When you speak of resistive heaters, is this what you mean? Can I remove these things along with the wiring?

image url)Yeah that's exactly what I mean, you can remove them

@ianlighting Try working out what that means? Should I go back to college and get an electrical engineering degree?

you can read what the error codes mean the Owners manual: https://resolve-ev.com/pdfs/owners_manual.pdf

@isak Now that I know what is shown on the OLED is an error code...this code is "Caution lamp and Charging stop" From the Owners Manual: These are all errors directly from the Nissan Leaf BMS, they are quite explanatory and should also be corrected immediately. A good solution to locate the error is to use Leafspy
and look for the errors the BMS experiences. One cause for the caution lamp and charge
stop error could be a disconnected BMS balancing wire. This will cause the bms to not allow
charging of the battery and limit the motor to 4.5kW of power.
It is recommended to use a bluetooth dongle and to connect Leafspy to your car for specific
diagnostics and to see the health of your battery.The LELink bluetooth OBD dongle came with my kit. Doesn't look like I can access it because I don't own an Apple product.
Is Leafspy an app or another piece of hardware?
