This pic is from a 97 seville. My 97 STS is not the same. I either have te wron switch, or i am missing a peice. The peice i have that the 2 vacuum lines go into is a black rectangular box with an electical plug. The plug from my wiring harness is plugged into it. The switch in the picture is NOT what i have (#2), and i do not see the square box in that picture.
Am i missing a part or do i have the wrong part?
I believe this is the cause to my 02 sensor codes and the 1441 EVAP System flow during non-purge code. I am returning a dead alternator to the scrap yard today and if i do indeed have the wrong switch i am going to look for the right one.
