If you look at the below pic this plug/connector sits right below the pressure chamber that sits next to the UIM. I took off the pressure chamber and found it not plugged into anything, and upon inspection i couldnt find anything that even looked like it would plug into.. Any ideas?

 

Looks like the EGR Switch connector. Only used in California cars. Someone confirm.

I believe it is unused. Look at the line diagram and it will let you know, it is here on The Forum.

I have perfect sequential spool and mine isn't hooked to anything.

"luneytune" is right I think, mine is like that also, never plugged into anything.

 

ok sweet

 

mine is plugged in...looks like it goes to the egr...

 

EGR switch.

Non-California cars do not use this.

 

Yeah, mine is empty too. I agree it is for Cali cars only.

 

Next time, please use a smaller pic.
