Any one know what this switch on my dash is for??

I have this switch on my dash, to the left of the steering column. My buddy has a switch there too, looks different from mine tho. He knows a guy that has one that looks exactly like mine and said it has something to do with "gas"

So i thought I would put it out there to the experts. BTW, I have factory fog lights, so it doesn't turn those on. When I drive and hit the switch on and off it does nothing that I can tell.

Thanks

Well it's certainly not stock. I'd follow the wires and see where they go. It may just be a dead switch that used to be hooked up.

Did it have airhorns on it? I have a toggle switch on my E150 van for my dual gas tanks.

kind of weird that the only three guys I know that have these trucks all have one in the same place though

I definitly dont have airhorns or dual tanks.

Tried it as a "high idle" ? Start truck, set parking brake flip switch does it rev? Other than that, your guess is better than mine!

I will try that. My truck does idle high a few min after it starts up. never noticed if it was with the switch on or off though.

On cool-cold mornings they will idle higher after a couple minutes on their own. But not as high as "high idle" it will go to 1200 rpm.

thats not it then bc i have had the switch on for a week or so. truck does its own high idle thing after a few mins.

So, what color wires is the switch hooked to? mainly the one going out of switch.? Good place to start. Have fun!
