RAMPS 12V Output Pin

I'm building a Prusa i3 with Ramps 1.4, and I'm trying to install a hall effect sensor as the z min endstop, but it requires 12V, not the 5 that are provided on the endstop pins. I was wondering where a good pin that I could get 12V from. I'm already using the 12V out next to the X-stepper driver for my extruder fan. Does anyone know any other 12V outs?

Thanks!

Connect it to the power supply.

12v aux (just behind the power connectors) If its not already in use..

Other than that the power supply is the only option.

I've soldered wires to the 12V AUX connector and a 5x2 male connector. Now I can feed 5 different consumers with it.

I did something similar with a strip of veroboard (stripboard) - the only thing to remember is that each copper strip can only handle up to 0.5A. I soldered some single-strand wire along each strip to boost capacity.
You will also have to ensure that the connection strip doesn't touch anything it shouldn't as everything is a bit exposed. I put mine into a box (STLs attached) - the input wire goes through the narrow slot, and the output wires go through the wide slot. When I made these the lid was a snug fit, but you may need to use some tape or glue.

I ended up doing something similar.

I just soldered a wire to two header pins so now I have 2 positive pins.

Thanks for the replies!
