Been through all this myself as I used to have an Autolite alternator with a Autolite regulator on my car. I've now fitted a Lucas Dynamo (with alternator hidden inside), to get back the proper cable tacho drive to mechanical tach... but I've attached my wiring diagram which took ages to work out for an electrics-hater like me. This is Lucas wiring and colours, but it should tell you enough about what you need to work. Obviously, the car has ammeter and ignition warning light. Hope it helps! I should mention - I've driven 3,000 miles with it as the diagram with no issues.
