Default Replacing Generator with Alternator needing wiring instructions

The schematic I have on the 2G and 3G alternators shows a 510 Ohm resistor across the Gen light and a 20A fuse in place also. It also shows that lead coming from the Voltage Regulator goes to the Ign contact on the key switch. Other schematics show the resistor going to the ACC contact. I know this is doable because mine is working and others on here have made it work also. Here are some schematics that I have. Dave can get this sorted out for you, I am sure. The last two schematics are for later Buicks, so I do not know if they apply here.
