vehicle electrical advice needed

[magpies]

I've fitted a modern Bosch 120A alternator to my 1988 car.The old alternator only had 2 connections = large main output to battery and a wire to the dash warning light. The new alternator has 3 - the main output and then a 2 pin connector which is the lead to the dash warning light and also 12v from ign switch I think. I can attach photos - I need to know which of the 2 pins is which connection.

Thank you Mr Road



I did try but didn't get anything like that - searching can be fun
