I assume you mean the internal regulator GM style.

If you don't have a 2 wire connector for the regulator you can buy one at NAPA. The larger red wire goes straight to the stud that the battery feed wire goes to. the smaller white wire goes to the bulb. The bulb will need 12V KO on one side, the other side goes to the white wire of the reg. With KOEO, the reg is grounded and the gen light will illuminate. KOER, the white wire is not grounded (as long as the alt. is working) and the gen light is off.

I'll bet the origional system worked the same. If you have a wiring schematic and trace it down, you can tap off the OEM wiring at the old regulator.
