Here is the battery tub of a Leaf lithium pack in a 2016 Precedent that I recently completed. The only thing mounted on the original controller plate is the Run/Tow switch. Everything else is moved into the tub. No cutting or modifying of any factory wiring harness to reconfigure this way.

Another thing, the original CC wiring for the programming port can be reused to wire in a SPDT switch to the controller using three of these wires. Add the switch to three of the wires under the dash and pull the pins out of the 4 pin connector and reinstall into a 3 pin shell and plug it in. Ready to go. Removal tool for the pins is needed. Drawing attached was sent to me from Alltrax.

I like your spreadsheet too.
