race car wiring question, Alternator wiring really... Options

[brant]

Hello everyone... and thanks in advance.

I'm cross posting this, so if it reads kinda "weird" that is why.

I'm trying to do a wiring harness from scratch on a race car.
Its a 1967S 2.0/6 motor....

first question: Would this be an internal or external voltage regulator on the alternator? (I'm guessing its an external, so I probably need to wire a regulator in somewhere)

second question: I'm replacing the tiny alternator warning light with a LARGE warning light.... I've seen this on other cars but they usually had a full wiring loom intact.

a)Do I need to pay attention to the wattage of the warning light bulb to get the circuit to excite?

b)should I wire a resistor in line to meet this need of a particular wattage and then wire my warning light seperate?

c) if b is true, then how would I wire the light seperate?

d) help...?

that should about cover all my questions for the next 24 hours or so... Most of the circuits (ie: fuel pump, switched ignition power, etc.) have made simple sense... but I'm struggling a bit with the alternator so thanks a ton fellas!!!!

Later 911's use the switch pictured below to detect a broken belt. Wire it up to lights, buzzer or what ever. Using this you can tell the difference between an electrical problem or a broken belt. It would really suck to pit-in just because the voltage regulator crapped out.
