Late alternator into an early car?

[MG Steve]

Hi. I haven't been on here for a long time as my F has run very well!
It is an early car and the alternator has seized solid. I've had the car sitting for a while until I have found a replacement. I've now got an alternator but its a later version with the different connection on the rear.
My questions are: Can I use this later one and if I can, what are the correct connections for the wires?
The original unit had a large crack in the casing so not worth doing anything with other than throwing away. I've already removed the crank pulley to clean the fused rubber out of the groves.
Thanks in advance.

yeah, in the end this is a part that dies on ever MGF or TF. Have been told that technically it should be possible. you have to changer the wiring connector and the later one has an extra connection that is not on the early cars and can be left out. But I did the expensive path and bought an original oldie. So haven't done it by myself.

Hi and welcome to the forum

There is no problem running the later alternator on the older car.

The extra wire is connected to the MEMS3 ecu and isn't essential for the alternator to work.
