93 runner w/ V6. A friend's rig, trying to help her diagnose her starting problem, and have found lots of good info here so may be back later with questions (I have an LC, so not familiar with 4Rs). But this is about a plug hanging loose that I would like help IDing. It is located directly behind the battery (PS) and I wonder if its just unnecessary or needs to be plugged. Be great if getting this to its proper home would solve her problem, but I don't think so. Will be working in daylight tomorrow, tonight couldn't really see where this should go if anywhere. Thanks in advance for anyone who can name this:
