Last T5 question i promise

of course im a noob at soldering. theres 2 wires per input. how do i know which one goes to the grounded spot? does it matter? i know im asking alot of q’s but this should be the last one. any help appreciated thanks

Either will work going to ground. Just make sure only the grounds you choose go to ground, switching them up for one button will cause it to flip out.

sweet! thanks
