did an engine change on 2008 Mazda 6 with 2.3. Have one wire that didn't get marked, or tape fell off. For life of me, can't find where it plugs in.

It's in front of airbox, photo attached. Any help greatly appreciated.

 

Does it go to the solenoid on the side/end of the airbox? Solenoid hs a vacuum hose that runs to it as well.

 

my airbox has a bit different setup. The only wires come into top of box. I've had it all the way out so nothing hidden. Vacuum line also comes into breather tube between box and engine too. Thanks for the effort, I appreciate it. Car runs great, temps and pressures normal, all lights signals good. So guess I'll swing it by a Mazda shop. Probably be a 2 minute fix for an old hand.
