Voltage regulator

I have gotten the second new voltage regulator now. This one looks like old style, but is much lighter. I had told napa, I wanted the transistor style, like the one I have been using. I guess they just put it in a can to look like the old style. Anyway, the new one has the white wire cut off of it. It is obvious it was never hooked to the buss on the back. Does anyone know what the white wire went to on the old ones? All I know at this point is, that this one works, so far with no problems:nervous:

Oh by the way, did I mention over the last week. The choke cable fried pretty badly. It's a wonder there was only minimal damage. The short harness connecting solenoid to main harness fried. Also melted side of fuse box where choke cable was laying across it without the fuse cover on it:dead: It is difficult to conclude what went first. I have a new choke cable from MSA on it's way. I also recieve my new ground kit from Courtesy Nissan yesterday.
