Mad Electrical http://www.madelectrical.com/ that Randall links to is a
"must have" bookmark for all automotive things electrical e.g. on their site
is a tab called Electrical Tech. Behind it you'll find a great tutorial on
the various Delco alternators that we use as an upgrade as well as things
like: Brighter Headlights, 1-wire vs 3-wire alternators etc. Dan Masters
turned me on to this site many years ago.

It's not trivial, but not terribly difficult either. Basically you have to
divide the electrical system into the battery and starter on one side (plus
perhaps the horns and the sense wire to the alternator), and everything else
on the other side; then connect the ammeter between them.
Assuming this is a 73 or later TR6 (earlier cars had ammeters), you can just
remove 3 of the 4 brown wires that go to the tie point in the battery cable;
join them together somehow (perhaps with one of these:
http://www.madelectrical.com/catalog/cn-1.shtml ) then run a pair of heavy
wires (10 AWG will do, but I'd use 8) from the old tie point and the new tie
point to the ammeter.
