Do you want to swap this into a Tesla car or into a conversion?

Into conversion

Link works fine for me and I can access documents (see screenshot)... maybe it's an issue with your browser (I'm using Chrome)... why not try looking up that error message?

I can access these file through chrome. Thanks,But I could not find any references regarding junction box connection.
On page 20 of 2014.2_ModelS_RHD_Release.pdf only give you High voltage interlock connections reference.

You don't actually need to control anything in the HVJB in order to use it with the Gen 2 charger for AC charging.

That’s good,Thank you jack,I was assuming that high voltage contactor may work by supply from that 12 port pin.

Here's a thread with lots information on the HVJB from the Model S (pre 'face lift' models);

Here's a link to the schematic for the main PCB;

AFAIK no one has published any detailed information on the control board in the HVJB.

As 'Jack' says, you don't need to do anything to use the HVJB with the Gen 2 Tesla chargers. Controlling the contactors in the HVJB will only be required when we start DC charging via a Tesla CHAdeMO/CCS adaptor (which is awaiting the next version of the charger control board).

What about controlling the contactors in the Model S gen 3 charger with a V3 Open Inverter control board?

I'm struggling to find current information on the charger controls. There's a decent amount of information here concerning specific issues with earlier revisions of the control board, but I'm at a loss for current information. I'm trying my best to teach myself and not rely so heavily on everyone here, but I could use a little pointer. The Tesla subforum doesn't get much traffic currently, and only goes back to 2019, but I think the charger boards were in development prior to that? Is there an archive and can I access it?

I've also found some minor discrepancies within the documentation on Damien's github. Is that the latest and greatest publication, or is someone else keeping the newest revision? How do I submit corrections? Does anyone care at this point?
