So I was pulling the meth kit out of my Evo today and this thing was next to the power switch on the lower dash. It has 2 buttons a + and - and a little window that has numbers 0-9. You push the + - buttons and the numbers change..simple enough. I always thought it was a part of the meth kit but it wasn't hooked up to anything. Anyone know what this thing is?
Meth kit came with the car when I bought it and I have no use for it as I'm running e85.

 

Got a closer picture of it?

 

Water injection switch?

 

The meth/alk kit is an SMC, theres nowhere on the controller for this thing to hook up. There was a fail safe in the engine compartment as well, which didn't have an open connector for a plug like this. The wiring and plug look almost oem.

Here is a better picture.

 

It goes to a piggy back ecu to switch maps. I cant remember the brand but I've seen the subi guys use it.

 

It goes to a turboxs utec piggyback

Ahh sweet thanks . I wonder if the utec is buried up under the dash somewhere still.

 

Pull your glovebox, takes about 30 seconds to do and you'll be able to see it, it's pretty hard to miss.
