The hose you need to connect to the butterfly diaphram is located toward the back left of the throttle body, as you are looking at it. When I put mine on, the instructions were incorrect (that was four years ago). A quick call to Kury put me with a tech and he knew exactly what was wrong and told me how to find the right one.
The hose you need goes to a 'brown thingy' under the tank with two or three other hoses on it, you will need to plug the nipple you take the hose off of. Mine was just the right length to go to the hypercharger without cutting. My first hookup was per the instructions and the butterflies didn't work. Call Kury at the phone number in the instructions, great folks, very friendly and happy to help (and they know what's what!!)
If you don't have an answer on here by tomorrow, I'll get my manual out of the shop and tell you exactly what hose, where and what to do. (I ain't going out to the shop tonight....sorry
)
