How to install a 3-way light switch:

First, ask the google to show you a couple videos about installing 3-way switches. That way, you’ll find out that you need a four-strand wire to make them work before you do something stupid, like buying a hundred feet of standard three-strand electrical wire.*

The 3-way switches that I bought came with instructions printed on the insides of the boxes they came in. Throw them away. They will only confuse you. If you need a wiring diagram, ask the google again, review a few wiring diagrams until you find at least two that you understand, make a sketch your damned self and work from that.

If you run standard three-strand wire (hot, neutral & ground), you’ll have to run two lengths of it because you need that fourth wire to make the switches work. This is going to sound really obvious, but do it anyway: When you run the first wire, mark each end of it with a pen or piece of tape or your own blood. You’re not bleeding? Have you stripped the insulation off the wires yet? Do that. Okay, now mark the ends of the wire with your blood. Do not run the second wire until after you mark the first wire. If the reason for this isn’t apparent to you, you really need to just shut up and mark the ends of the wire. Then run the second wire.

There are three screws on a 3-way switch. One of them is a different color. This is important. If you don’t understand why, ask the google!

The first time you try out your 3-way switch, it might not work the way it’s supposed to. If it doesn’t, go take a nap, or relax with a cup of coffee and a newspaper, or surf the internet for cat videos. Don’t try to fix it right away. Leave it alone for at least an hour. After you’ve calmed down, go back, take everything apart, and start over from the top.

If it does work the first time you try it, you’re a better man than me.

*It’s not like I won’t use the wire. I will. But it doesn’t make me feel any less stupid about not knowing that four-strand wire exists explicitly for this purpose.
