Yes, it is ok to leave it unhooked. Won't hurt a thing.

Thanks, I ended up grounding the gray wire from my 4 wire o2's, (The gray wire went to a empty spot on my car harness for the o2's).
So far so good, I lost my o2 codes and hopefully will road test the car today.
Thanks for all your help, I'm sure I'll have more questions.
