Recently brought a new alternator for my '97 MX5 from Ebay.

In the picture the old one is on the left part number: A5T03677A
The newer one is on the right and came from a '91 MX5: A5T03677

As you can see the new alternator which was fitted to an older model has an extra plug. The one I want to replace has a hole but no plug?

Does anyone know what this plug is for and can I run the new alternator with nothing plugged into it? Or do I have to buy another alternator

Thanks Steve
