Problems are escalating help

Ok had a guy replace the knock sensor 2 for code p0330. He did an awful job now I have hoses that are not hooked up and have no idea where they go. Still getting code p0330 and also p0171. Car running horribly. Started blinking check engine light couple days ago but then went completely away but is now back. Also a piercing whistling sound is coming from the throttle body. Sound is goes away when accelerating.
Help me! Does anyone have a hose diagram for dummies

You may have to do the knock sensor bypass or relocate procedure to get out of limp mode until you can get a proper repair- can do a search for "how to" and se how other members did it.

What did he use for the replacement knock sensor?
Brand and Part#?

The sticker gives clues as to how they are connected to the various objects ... some objets have more than one connection and the diagram gives a pictorial connection.
