This wire connects to a coil in the regulator and turns on a contact when the voltage goes above 3.2V. Once the contact turns on in the regulator the #3 and #4 terminals are connected together. Terminal #3 is battery power so this puts battery power on both sides of the bulb and turns it off. This means the brown #4 wire should go to +12V. gahi's diagram is the correct way to wire a GM 10SI/12SI, and utilize all the benefits of that great design. The output and sensor wire (#2) should go to the main power distribution location, as shown, not to the battery. The #2 wire ensures the 14.4 or so output is fed to the entire system, eliminating any voltage drop. Voltage regulator wiring diagram chevy
