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:

wires (10 AWG will do, but I'd use 8) from the old tie point and the new tie
point to the ammeter.
