Rb25 alternator wiring

[Full Lock]

Hey guys i recently did a rb25 swap in my r32, ive had it running and tuned few times since but i have a left over small wire that im assuming hooks up to the alternator.. any photos would help cheers.

It is hard to tell for sure from the picture but it looks like a ground wire.  I would attempt to follow the wire and see where it goes.  On the swap i am working on I believe there is a large ground wire that is bolted to block around the engine mount and connects to a bolt on the side of the front frame rail.  When you did the swap did you use the rb25 transmission harness?
