This manual is very well outlined and easily understood. A diagram of the location of all electrical components under the dash and surrounding the steering column is absent from this manual. Wiring diagrams indicate electrical pathways but do not show the physical location of components on the car. I found this manual lacking the one thing I needed most, component identification and location.
