You can found this DIY on http://www.sequoiatravels.com/2017/05/enabling-fog-light-with-parking-light.html

Are you getting tired of fog light no turning on when you turn on parking light? Are you getting tired of fog light get cut off during high beam? I found a mod which cost less than $5.

There is a way to turn on fog light when you are turning on parking light or on high beam. Here is a diagram show you how to bypass the circuit.




You need need the following parts. These parts cost less than $5 or maybe free if you previously purchase some. This is a very common electrical part.



To bypass the fog light relay, you need to cut 2 wires and connect these 2 wires together. Using the above parts, you will be able to switch back to OEM if needed. If you don't need to switch back, just cut the 2 wires and connect the 2 wires together.

The following solution will enable your Fog Lights to be “On” any time the main. light switch is “On” in any position as follows.Turn Parking Lights “On”,
  • Turn Fog Switch “On”, Fog Lights Turn “On” (NEW Function!!!)
  • Turn Head lights “On”, turn Fog Switch “On”, Fog Lights Turn “On” (Same as Factory Setting)
  • Parking and/or Headlights “Off”, turn Fog Switch “On”, Fog Lights “Off”(Same as Factory Setting)
    • If the Main Light Switch is “Off”, the Fog Light WILL NOT work in this design.
  • Turn High Beam Lights “On”, Turn Fog Switch “On”, Fog Lights Turn “On” (NEW Function!!!)
