Automatic fog lights

bluemonstercali · January 15, 2021

Had anyone tried to make the fogs turn on automatically when the headlights turn on?. There was a write up on here for my nnbs where you added a wire and resistor I believe as a jumper from relay to relay in the fuse box. Essentially making it so that when the headlights relay was activated it would jump and power the fog relay. I installed the hack and it worked absolutely flawlessly for 12 years before I sold my nnbs. It removed me having to hit a fog button on the dash every single time. In my opinion it looks better with fogs on.

Boostautoparts.com has that.

For 20 bucks it's worth it. Here is the link...

One way diode will do the same thing and cost pennies

I also just ordered the harness from Boost. It should arrive late this week and I hope to install it next weekend.

Boost kit is great. I got the “all lights” kit. Fogs on with headlights and stay on with hi beams.

Easy, cheap, quick and no wire taps.

Does the fog light symbol still come on the dash with this mod when on, or no?

bluemonstercali · January 23, 2021

No it doesn't

Okay, thank you. Is there any way to retain that feature with them automatically coming on with the headlights?

No

I just installed my Boost Fog Light modification and it takes about 10 minutes. Hardest part is separating the wires for the tap. I also called Boost and they told me since my vehicle has the Auto High Beam feature, I will retain this feature and my foglight will remain on too. If I recall it was like $20 and money well spent.
