Default Vaccuum leak help.

I am trying to chase down a vaccuum leak that is causing an erratic idle problem. I have found some hoses near the front drivers side headlight that are plugged off. Does anyone have a diagram of what should go where and if i even need all of these hoses. Most of them just wrap around stuff and go back to plug into each other.

what year?

there should be a vacuum canister that feeds the cruise and climate controls, depending on year.

This is for an 87, there should be something this on your radiator shroud.

sorry guys this is for an 87. There does seem to be some kind of sticker on the radiator shroud but it has been faded to the point of not being legible. That diagram helps though!!

This car has no egr and air system delete so can i just plug the lines that go to those items? Will that affect anything? Thanks guy for your quick responses
