I am in need of a vacuum hose diagram from a sc400. Ran searches for it and only got hits for sc300 diagrams.

Also need pics of how to locate the iacv and tps please. Im not motor savvy so all help I can get is much appreciated. Hoping that replacing vacuum lines and cleaning senors will get my idle issues solved so I can drive my baby again.

Hope I can solve my problem with u alls help
