Auto on fog lights

[jimmyboy8301]

I searched and couldn’t find if anyone has done it. I know boost automotive makes a kit, or you can just buy the $1 diode, but has anyone actually done it where you wired the fog lights to come on with the parking lights? Pin 10 to 22.

 

If so do the fog lights come on when you remote start the truck? Also I’m assuming they stay on with the hi-beams since they are wired with the parking lights?

Someone posted a video on this. Maybe helpful.

I saw that video already thanks, it doesn’t really speak to every time you auto start though.

He mentioned in the end @5:22, every time there's power to the running/parking lights the fog lights will come on. I'd expect that to happen during auto start, or even just on the unlock from the remote or door.

True, i wonder if that would have a negative effect on the fog lights

Yes they come on every time the parking lights are enabled. I used the diode method. And yes they come on while remote starting at night

Do they flash with lock/unlock??

What’s the diode method?

 

I did the boost auto mod on my Sierra. They come on with my running lights when remote started. I don’t believe they come on when unlocking. Granted I rarely unlock with the fob and use the keyless buttons on the door.

No they don’t flash with unlock. Only the turn signals flash not the marker lights.

Just use a 3 cent diode wire and connect the same two wires that the boost is essentially connecting. Just a less costly way. I've done it to my last 3 trucks over 7 years and no issues ever.

Here is another option fleceperformance.com/all-lights-on.html  small circuit board with a diode. I used pin 10 and 22 referred to boost for which pins to use for different functions.

so bridge the 10 and 22 pin location with the diode wire?

I understand a diode only allows current to flow in one direction, is there a certain spec/size diode you recommend using?

 

I would love to do this to not only my fog lights so I can have them on with Hi-beams.   But I'd also like to run a jumper to the work lights on the mirrors to use them as ditch lights when needed.

So how do I have both fog lights on with drl and fogs with highs. Do I need to jump 10-18 and 10-22?

Using a couple of stick pins, some wire and a switch makes this mod a lot easier. The stick pins will slide in much easier than the leads on the diode. The switch (connected to the wire, and not seen in the picture) allows quick and easy deactivation of the mod for state inspection, etc.
