Turbo Regal Wiring Diagrams
Diagrams scanned for GNTTYPE by Jim Testa
Since there have been so many wiring questions on the list, I decided I would put as many diagrams as I have on the web for you all. They are individually viewed, or you may download the complete zip file (system diagrams, or complete sectional wiring diagrams).

To save to your computer, let each image clicked load, then right click the image, select save image as:, then set the target directory, and ok. I hope these help somebody!
