I'm very new to using scotchloks. I know the obvious point of them is to splice a cable. But I notice mine has three holes. What is the point of the third one? Does it matter where you place your cables?
Is the third one just for example you need to connect three red wires for like a speaker system for example? Because I thought this was the case, but then I was looking at the wiring on my phone system the other day, and I noticed not all the scotchloks had the same color of wires going into it.
