Manual - Wiring Diagram

kind of vague. it didn't really help me much.

Very useful

I have a 69 Convertible that has power windows- I DO NOT know how to read electrical schematics AND I do not use this book very often BUT it has paid for itself many times over-this past weekend I used it to trouble shoot some power window wiring - basic stuff-just used the chart to make sure the color coded wires were in the right place AND was able to trouble shoot a problem and CORRECT the windows to make them work. Worth every penny
