What does this plug go to?

[Shadowfax]

I found this plug on the drivers side under the mc. Looks like it goes to a sensor or something.



truck is an 02. 7.3 auto.

That looks like an aftermarket plug...

Any mods to the truck?

looks like the air filter plug that disconnected on my truck, do you have an aftermarket intake

[Shadowfax]

Yeah have an intake. There is another sensor in there too that I know goes in the factory airbox but don't know about this one. I just got the truck and it already had an intake so I don't know what factory looked like. It leads into a big loom on the inner fender.

The wires are green/red and gray.

Good call!!!


There are two sensors on the factory air box on a 2002, one is the intake air temp sensor and the other is the filter minder (which will set a light on the dash if the filter is plugged)

Its one of those two.
