Welcome to ZDriver!

I suppose you are talking about the A/C compressor? There are two different versions... one for the turbo & one for the n/a. I suggest taking it back & getting the other.

this is the one for my car according to data specs

my car is not a turbo and this compressor is for then/a

Dunno what else to tell ya... if the connections aren't the same, it's not the right one.
