What does this hose go to?

[wango tango]

I’m going to have a heckuva time reconnecting the green wire on the back of the alternator. I don’t know what that little gizmo is. Does anyone? I googled the part number and it’s sort sort of electrical widget.

Does anyone know where to go to? Maybe the IAT, although it’s a different color? Makes no sense.

Looks like the hose is supposed to be open.

Anyone know about the green wire/widget on the alternator?

I believe that's the tachometer wire, I have a PDF of the tech manual if you want to look through it

It looks like the #RE520163a relates to the type of connector they use. There should be a way to unclip that connector from the back of the alternator....maybe a small screwdriver in the slot on the end? Don't force anything....you just need to find how it clips on. I think it is just a fancy anti-vibe connector Bosch uses.

Tach seems to work fine. Thanks for everything.
