Festiva Alternator conversion!!

Once again I've relied on my memory and it let me down! A "fiesta" alternator is a common conversion but I ordered a "festiva" alternator instead.
Great little alternator that will take up very little space but I'm not sure of the wiring.
It has the standard hot lead and the 2 spade's that form a "T" and then a separate spade that I have no idea of.
Have any of you fitted this alternator?

Appreciate the help!

From stuff I saved. Google Muenchausen's Garage

There is plenty of information on the net regarding alternator conversions for British cars. It's a common upgrade. I found the information at Muenchausen's Garage to be especially useful. In particular, the recommendation of the Bosch 13107 alternator, designed for 1978-80 Ford Fiestas, was spot on. This is a 55 amp alternator, which should provide all the current anyone with a bugeye Sprite could wish for; is inexpensive; and fits the Sprite almost perfectly. This is the unit I used.
Electrical Installation
The alternator has two 3/8" spade lugs marked "B+." Either of these is connected to the car's electrical system through a length of 10-gauge stranded wire. The old, mechanical regulator is no longer needed. The connections to the electrical system are as follows:
1. The wires from the A and A1 terminals of the mechanical regulator are tied together and connected to the wire from the B+ terminal of the alternator.
2. The wire to the F terminal of the regulator is disconnected and taped.
3. The wire from the ignition indicator light to the D terminal of the regulator should go to the D+ terminal of the alternator; the other wire to the regulator's D terminal, which went to the generator's field coil, can be taped and left open.
4. Any wires to the regulator's E terminal are grounded to the chassis at any convenient point.
The unused terminals on the alternator are insulated. A good method is to use a piece of shrink-wrap tubing. All unused wires dangling from the harness are tied out of the way, so their terminals do not accidentally touch something and create a short circuit.
A connection diagram is shown below:

Muenchausen recommends using two wires from the B+ to the car's electrical system. I suppose this can't hurt. However, invariably, in such arrangements the resistance of one of the B+ connections is a few hundredths of an ohm higher than the other, causing one wire to carry most of the current. In the end, I chose to use both spade connections on the alternator but a single B+ lead. 10-gauge wire is easily good for 30A, and I can't see the current, in this car, ever being any greater than that. The pictures below show the connection to the alternator and near the regulator; I plan to remove the old regulator, although it still appears in the picture.
 
The above description is in the Wiki under General Technical Articles.

The Festiva is just a later Fiesta, so I suspect it's the same alternator or at least very similar.

The only terminals you need to deal with are the B+ and D+; I seem to remember that there is another terminal, which you don't need to do anything with.
 
Thanks guys but the Festiva alternator is alot different!
Its tiny compared to the Fiesta alternator and I like the looks of it. Actually will give a little room in the engine compartment. Once I get a little time I will see if I can figure it out.
