About These Wiring Diagrams
Each wiring diagram is a high quality reproduction. It is an 8" x 10" blueprint professionally printed on photographic paper. It is suitable for framing.
This picture is an example. You will receive the diagram for the automobile you request. Just like the example, it will be a white diagram on a blue background. This blueprint is reproduced from a scarce book printed during the 1920s. As the preface of the book explains, "Each blueprint shows the complete wiring of all electrical equipment used on that particular car, and its proper use will greatly simplify the location and repair of electrical troubles."
Disclaimer: The blueprint is for reference purposes only, and its accuracy should be field verified. Because of the age of the originals (published during one of the most exciting eras for automobile development), defects may be noted that are from the original drawings.
Shipping Information: Please allow 2-4 days for processing time. Your purchase will ship within 4 business days. It will be packed carefully to prevent damage during transit. First Class Mail to both the USA and Canada is free. If you live in another country, you will be billed the actual shipping cost.
