Wiring X-controller

Can anyone give some advice on this? Do I sauder these or do they connect a certain way? I am starting with my X Limit. Any help is much appreciated

No soldering required. The internals have connectors that snap together. For the external wiring you’ll just need a screw driver.

I have gotten the wiring to back of x Controller complete. I think I have missed a step. My Y limit end needs to be connected
