Default Alternator issue

Hi all
My charge warning light has come on and multimeter suggests alternator is producing considerable changes in voltage.
This seems to point to alternator malfunction.
I have the chance at a cheap 120amp alternator, but I'm not sure if mine has 2 or 3 pin plug. Does it matter?
Car is 2002 cdt.

p.s. can't check as car is roadside and I'm past getting under the bonnet!


Thanks
Geoff

yes it does matter. I'm not sure either one is interchangeable.

You can fit a three pin alternator onto a two pin harness.
