This need to be connected on the intake right behind/under the air cleaner. Take the air cleaner off, and look right behind the F-distributor, there should be a 2 way connector. Another way of finding the connecter2 way connector is that follow your main Vaccum line which connects to the 3 way check valve next to the brake booster. It is a little challange to connect this due to lack of visibility and not enough space.

Hope it helps
