What switch could this be

So I'm putting in a gps switch here and I found this taped up. I'm pretty sure this is a oem wire harnesses. I had a blank in that spot. That pig tail was plugged in there just like that. I'm pretty sure I've seen stock switches in that spot but since mine is a base model it didn't have them. If you know what goes there or know why that funky pigtail is there for please let me know.

 

I think my fog light switch is located there.

 

Ok thank you.

 

Looks like someone tapped it for power.

 

I'm pretty sure they had it as some kind of hack cuz I'm almost positive my fog lights worked when the headlights came on. Now they don't but I ordered a fog light switch.

 

Thank you, I really like your drawing

 

Wait, you have fog lights, but no fog light switch? If so, somebody kludged together some kinda wonky circuit to make them work. Just plugging in a fog light switch may or may not work.

 

Could be blue wire from Fog relay to a shared ACC switched ground...

 

I bought a $30 used one on eBay so will find in a week or so. I swear my fog lights worked though. I could be wrong it definitely wouldn’t be a first time. Lol

 

Look under the front bumper and see if the fog lights are plugged into the factory harness. If they're not plugged into the factory harness, and there's no foglight relay in the underhood fusebox, plugging in the switch won't do anything.

 

Oh good point. I’ll look for a relay when I get a chance. I didn’t even think of the relay.

 

What I'm getting at is that maybe whoever installed the fog lights may have just ran a wire from the fog lights to the headlights.

 

It was a fleet vehicle from Canada and I got like 5 keys with it when I bought it. Anything is possible. I’ll figure out a little later. I’ve been tinkering with the truck putting in a Gentex mirror, hard wiring my gps and smoking a pork shoulder. I’m at the store now I’ll look at it when I get back.

 

I do have the relay and I'm pretty sure the factory wire harness too.

 

It is

 

That would trigger the relay to turn on the fogs...

 

Oooooooohhhhhh, I see what they did. They had that jumper connecting the blue wire to the white/black wire.
