1972 olds cutlass wiring diagram

anyone have one? i will need a good idea of what I need to tap into for my ignition system. Also, What's a decent way to have a higher amp alternator. Should I convert it to an internal regulated alt? How should I go about that? Thanks...

Have attached a higher resolution image of the 1972 A-Body wiring diagram. The one referenced above is low resolution and extremely difficult to read.

I replaced my alternator with a internal regulator. There are some threads regarding the wiring changes. Joe P (old Fart) had posted a diagram. This is the link to the thread with a wiring diagram.

No 1972 Oldsmobiles came with the internal regulator, which makes that third-party wiring diagram suspect. What else did they get wrong?
