If you want to know how to wire a 3 way switch but cant find a decent3 way switch wiring diagramanywhere. Never fear, its really simple to do. All youll need are 2 SPDT- single pole double throw switches, or simply put, 3 way switches.

  • Youll have 4 wires, the 2 connecting to the led and battery power are your common wires, and the other 2 connecting to the terminals, or loose ends of the common wires, are your travelers.
  • Start by wiring the common wire of the first switch, this one should connect to the power source.
  • The common of the second switch needs to connect to the load.
  • Wire 1 traveler from the one switchs terminal to the terminal on the other switch.
  • Repeat the process with the second traveler.

Finally! One I can help with! I understand why you want to do it this way because you can turn the lights on at the bed then turn them off inside the cab.

We did this same exact thing for my buddys truck. Its simple to do. Its the same concept as a hall light in your house that is using a 3-way system with 2 switches to control the lights, one switch at each end. Instead of using spst (single pole single throw) switches you will need spdt (single pole double throw) swithces AKA a 3-way switch.

Radio Shack should have small ones that you can pick up pretty cheap. The wires that attach to the battery power and the LEDs is known as the common and the other 2 wires are travelers. These can be flipped at one end without any problems.

They just allow the switches to work together to change the state (on or off) of the lights when either switch is flipped. If you think about what will happen in the pic when one switch is flipped it might help you to see how it works. You just need to make sure that the common is in the correct place on the switch. Good luck and If I can help any more just let me know!

I promise it will work. You need to remember that these are NOT SP (single pole) switches. They are SPDT (single pole double throw) switches.

Cab switch UP Bed switch Down State OFF

If you flip the cab switch you have this

Cab switch Down Bed switch Down State ON

Or the bed switch

Cab switch Up Bed switch Up State ON

Its simple. If you change only one switch, either one. The state changes.

Another option is to install a third switch that is a DPDT variety and be able to turn the lights on or off from 3 separate locations. Such wiring configurations are used on 2 story home homes with a basement for staircase lighting, with lights installed on 3 floors. Wiring for this configuration can be found on the web. Marshall
