I had the same issue, you need to lay down under your diffuser with the top of your head facing front and your eyes looking up and then if you tilt your head up looking behind the bumper where the mufflers were you can take your hand and feel behind the bumper inside and there should be a little 1/8" vacuum line that is about 4-6" long.
