There is a company that supplies Old Mopar Manuals on CD Rom.
WWW.MOPARMANUALS.COM. I got 1 for my 72. It was a great investment. One of the nice things about it is that you can print off the pages you need, ie. a wiring schemaritc then you can write on it, spill coffee on, get greasy finger prints on it, whatever. You can always go back and print off another set.
It may help you out with this and future problems.
