RAMBo plug types

Hi everyone, I might have a stupid question:
I am trying to find out the plug types for the 2 pin mofset outposts on the RAMBo.
I would like to connect it to wire leads, so am looking for a screw type of connection on the plug that lets me attach wire leads to the mofsets. Without soldering.
Anyone know the name and where to purchase?
Cheers

I had a further dig online and found them on Ultimachine website.

Are they these Eurostyle pluggable terminal blocks at 5.08mm pitch correct ones for mofset outputs?

They are. Make sure you use wire ferrules when adding wires to them. DO NOT USE TINNED WIRES.

Thanks insta.
I also read online that all mosfet outputs are PWM regulated.
If the heat and fan is set at 100%, does that mean I will get the constant on 24V DC from the power supply?

Tinned wires will creep over time in screw clamps, leading to failures.
If you set the output to 100%, it is "on", not PWM'ing. I don't know Marlin's behavior if you disable the temp sensor and command it to heat, though -- that's why I suggested the sensor 999.
