What exactly did you do here?

Can you explain with a bit more detail/description of which wires you were connecting? There are specific locations the charger wires are supposed to go. If not, you can damage the charger and or the car systems.

I plug the + of the charger on the +72V of the psdm and the - on the -72V of the psdm.

This is also not a very good idea. Back feeding power into car electrical systems without knowing how everything works is a very good way to destroy hard to find and expensive components.

Instead of trying all sorts of wildcard tricks “just to get it to light up”, I highly recommend getting to know the car systems first, solve the issues that you know about, and power up the car properly.

I look at the this schematic to wire from the 12V battery to the psdm by the DC/DC converter plug
