The connector at the lower right corner(blue and yellow inside) is not connceted to any thing in my car.
It is located right behind air pump and below y-pipe-to-intercooler pipe (black plastic duct). I haven't had any problem so far.
Does anyone know what it is suppose to connect to?

Thanks.

 

I think that's for the cars that have the egr plug. It's unused on your car obviously.

Edit* You also might want to plug those LIM runners so nothing falls down into them.

 

that is for the automatic cars. Unless you have auto you will not use it.

Or the EGR as stated above i can't recall exactly..
what year is you car?

 

It's for the EGR. It's only used on 94+ and 93 Cali cars. For all other cars, the connector is still there, but it's unused.

 

Mine is '93 touring with manual transmission.
Oh, by the way, the picture is from someone else's thread, not mine.

If you plan on vacuum hose job, it is a good web site with lots of pics.

I found that connector while I was working on the oil leak from the rear turbo oil return line. I had to take off air pump and y-pipe to get to the banjo bolts.
I changed copper washers (or gaskets), and it's now leak free.
I took off precat, too. I should have replaced it with down pipe, but the down pipe arrived a little later. So I'll have to do it again.
But next time it'll be a little easier because I put anti-seize compound every where.

Thanks.
