Alternator question

Thanks so much I was wondering about that. I do have two wires that run to the voltage reg from the alt though. The Alternator rebuilder told me the one is for field and one is for ground, so I guess I will try and ground one and leave the other going to the voltage reg? What should I do with the other wire/ This will mean only one wire from the alt will be going to the voltage reg.
Thanks Cuda
