I need to figure out how to hook my tool sensor up. I have a sheet that said input5 pin. But don't see that on my board.

To get the best support from forum members, I am sure they will need more details from you such as the type of controller board and sensor you are using. I am sure you will have a solution soon after that.

I have a CNC USB Controller MK3/4 from Planet Cnc. The sensor is the one that came with machine. Round button with a wire to button and a wire with alligator clamp. Hope this helps

I'd also suggest that you, when time permits, terminate your wiring with good quality and correct sized crimp lugs.
A single loose strand can cause no end of problems

That's a dodgy looking black wire connected to board below the filter.
