Non-Inverting Cable ASS030550200 resistance to pull RX to GND on an MPPT

I want to switch off my MPPT with ignition on. So I have to pull down RX to GND, and therefore I prepared the mentioned cable with a JST plug.


But I recognized that on a high signal the resistance between COM (black) and REMOTE (red) is still some 52kOhms. Is this too much to pull down RX to GND or will it work?

As I recall, Rx has a pretty high impedance, so it doesn't take much to pull it down.

Sounds good. I reckon GND to be on the same potential as system/battery ground?
