Dodge Caravan wiring diagrams can be read in a Dodge Caravan service manual. Nearly all vehicle service manuals contain a complete set of wiring diagrams and a key explaining how to read them. However, manuals can be very difficult for inexperienced people to read.
Official factory service manuals for all Dodge vehicles from 1981 onwards are available through the Mopar Tech Authority website. This website is accessible in the Owner's and Service Manuals section of the Dodge website, under the Owners tab in the Dodge home page menu bar. Manuals are searched for based on the year, make and model of the vehicle.
