1997 maxima drive him coo coo

Hi guys; we need some help. My fiancee’ is replacing the starter on the only car we have and nsa today off only. He has to be back at the refinery in A.M. The problem is there are 2 wires coming from the solenoid, one is not hooked up to anything and we can’t find where it goes!!! Help please! SOS!!

Can you post a photo?

Or better yet, he should either get a repair menual at the local parts store or try googling “1997 nissan maxima starter replacement” for instructions.
