Also, Nissan is dragging its feet on refunding me for the VCM replacement ($960~)
I'd try walking into a shop, with pictures and printouts to help explain what you're asking for. This might help reassure them that you're asking for a simple splice to a 12V circuit and not asking them to deal with high-voltage EV components. Tell them the dealer wants to charge you $2800 for a diode. That might help to get their "fight The Man" dander up and help you out.
Here's another page that gives more info on the role of the diode: https://hackaday.io/project/9051-j1772-ev-simulator
