Which connector does the thermistor connect to on a A20M

I got a A20M and have figured out that it is missing the thermistor. Where can I get one. Can anyone tell me which connector the thermistor plugs into? I think it plugs next to the green connector which goes to the heater itself. There is a two and a three prong connector vacant, and I suspect it does connect to the two prong connector. Any help will be very much appreciated. Hopsing

Hi, Can you provide a picture of your adapter board

Hot end or hot bed?

Yes I can provide a picture but I don't know how to upload it. It is a jpeg file.

Yes the thermistor is the only thing that is missing. Heater is ok I think. I know where it connects it is color coded (green).

William thank you so much for the detail image. I thought that was the plug but I wanted to make sure. I now have a heated bed and heat to the nozzle but no movement from the stepper motors or extruder units. Any ideas as to what to check here? I am a newbie and I am sorry that I am a pain. Been trying for a month to get this printer up and working.

Hi, do you mean the extruder can't heat up or the extruder motor can't move normally?
The reason the extruder can't heat is that you haven't terminated the heat,
If the extruder motor cannot move, you need to check whether the wiring on the motherboard is correct.
If it is correct, you can exchange and check with the motor wires of other shaft motor ends to confirm whether it is a problem with the motor wires of the extruder.
