Both look like they have the correct plug so you shouldn’t need to do any soldering as long as the wires are long enough .. hopefully!

The JGAurora A5 & A3S Bowden coupler fail very easily. It is very hard to find a replacement, as this particular coupler is very uncommon. The fitting is a 4mm pneumatic coupling, with an M8 screw fitting, but with a 1.0mm fine thread. A 1.25mm thread will not work.
