Hey, all y'all Miata powered folk!
I am in the process of (hurriedly, and at the last minute) installing a first-gen Miata alternator on the Ford 5.0 motor in the Slotus. (Don't ask, it's too long a story, kids would get restless, grownups would snore...)
I have a bit of a problem regarding wiring up the little beastie. See diagram below:

See the alternator, the circular item near center of the picture? OK, there's three wires. One, the main output of the alternator, is a threaded post and that wire goes direct to the battery (or the pos lug on the starter). Found him, no problem. Then there's the other two wires. One -white/black stripe- goes thru the indicator lamp or the resistor and connects to an "ignition on" fuse. I understand the alternator won't properly charge without that circuit/wire. The other wire -white with a green stripe- goes up around the corner and connects to the 12v output line. I understand it's the input for the voltage regulator.
OK, here's the problem... I don't have the factory plug that connects to the two spade connectors on the side of the alternator. See picture below:

There's two spade connectors in that light brown plug. Which one is which???
OK, answers from the crowd! Anybody? Don't be shy, speak up...
