Which wire where????

Which wire where????
The alternater on my 88 3.5 has had the gong however I have an old one of a carby motor that I used to have. The one that has carked it is a Lucus, the old one is a motorcraft. I want to swap them if I can but they seem (or are) different. Hopefully someone can tell me if and how to wire it. Pics below (maybe)

It can be done....
You can see terminal markings on the alternator you want to swap in (D+, and two others - can't read them, and can't remember what they are
) One is next to the post where the capacitor is screwed on.
I believe I can also just make out on the old one the same markings, in smaller letters (i could be mistaken, but they should be there, most have them) In this case, all you need to do is make sure the wire which went to D+ on the old one goes the same terminal on the new. I think on the old one, just above the post with (white/gray), I can see something stamped. If you can match one of the smaller wires, the other one will be self explanatory, as the big wire is pretty obvious!
At a guess, I'd assume that brown yellow goes into the same plug thing as on the old (lucky theres only one terminal in there!) and the white/gray goes to the screw where the capacitor is (since there is a stamped D+ there), but check to see if you can match up the letters first.

84 Rangie, 3 inch spring lift, 2 inch body, Megasquirted 4.6, R380, rear Maxi, 34x11.5 JT2s. Simex FM installed.
The B+ is the heavy wire to the battery, the D+ is the ignition light wire.
The other wire on the Lucas is the tacho wire , I think the white grey and usually labelled W. You will not have a tacho working unless you wire in a field wire, or preferably get an auto electrician do it.
Just check the small wire is the D+ by shorting it to the engine with the ignition on, the ign light should come on.
Do not short the big one unless you want to see pretty sparks.
