Hello,

I am trying to make my mind up on what controller I use in my build. The EV controls T1C and T2C both stand out as easy to integrate options. My main concerns surround my use of a PDM and power delivery changes it causes.

Specifically I am a little confused by the pinout for a tesla small drive unit. On the T2C pin 10 is listed as 12V inverter power with Pin 13 being ignition switch power to the controller. It seems to be described as an output not input to the Drive unit.

But then on the diagram of how to wire it up and where I think I may have compatibility issues Pin 13 just disappears as a used connection.

Anybody wired this up and know whats going on there?

Pin 13 is not connected on the DU.

Pin E3 is connected to the switch from the controller. The controller then supplies power to the inverter.

Which is consistent between diagram & table.

I would have thought you'd need to connect 10 & 13 together at the inverter if the inverter has a key switch input. Not a big deal to add if it sits there looking stupid.

Why aren't you asking the people that make this thing? Is their after/pre sales support that bad?

I've PM'd you, so please check your messages.

I sent them a message as well. Just haven't heard back. Figure somebody here may have already seen this and known the answer.

I guess what confuses me is the table Says inverter pin 13 is connected to terminal E3

Where as you mentioned E3 is connected to ignition and not the inverter plug
