It's directly beneath the linkage bracket, should be two connections on top tee. Bottom fits into large rubber hose.
Be careful since I just did the same and broke the plastic tube that runs along the firewall. See my post at near the bottom of this section.
Unfortunately, the new one from Autozone did not fit properly so I put the old one back in. The old unit looked good, was very clean and the spring was still strong.
I got 110K on mine.
