I've purcased a Bosch alternator ( model number 2310054B61)from a Nissan Micra.
I don't have a conection plug with it.
And don't know where the blades connect to. I guess Threaded rod to Battery live.
1. to earth, 1. to dash warning light, 1. to Live (fuse box.) the other would go to the ECU but I dont need to use it.
But what ones to where and how do I find out?

According to the Hella catologue this is a 65 amp alternator from either a 1l or 1.3l 92 - 96 Micra.
With the keyway uppermost the pins are (from left to right):

Unused, Battery sensor, Lamp, Unused

thanks Mix.
If I'm reading this correct then 1&4 are not used.
2 is to battery sensor
3 is to lamp.
