More, (But simple) wireing questions.

[Targus]

Hi there,
Welp, my Thing is almost finished but I ran into a couple of minor setbacks. I have a generator setup and there were 4 wires comming off of the voltage regulator to the generator area. I know the big red one is positive and the green one was the neg. but I still have 2 more wires to deal with here. The problem is that the wires were so bad off that they melted in the sheath and 2 of e'm came off the regulator. I have no idea where. The car came without the engine so I had no referance. I'm thinking that one is a simple ground wire that goes to the screw at the back of the generator and then to the ground on the regulator, but the 4th one is a total mystery to me. Anybody know where that one goes?
Thank's in advance!

I think I got it.
One might be for the backup lights and the other is probably for the choke.
The duel Dells and the fact that I haven't played with a volksie for 8 years threw me.
