i need a engine diagram for a 1999 5.2 liter dodge durango?

Answer 1

You can get a Haynes manual for it for about $15. They usually have pretty good wiring and vaccuum hose diagrams. If that won't do, see your dealer and get a factory service manual. They are expensive, but worth it when needed.

Answer 2

You didn't mention the type of diagram you need. Most all, electrical or mechanical may be in a repair manual you can find at your local auto parts store.

An electrical wiring diagram may not be there thou. Armed with your VIN and proof of ownership you may be able to order one through your local Dodge dealer.
