can someone help wire issue So car has been running sluggish, backfiring, hard start at times. Brand new walboro pump, brand new manual FPR, new fuel filter, so figured it could be time for new opti. Have the water pump off, and while I was taking hoses off, I noticed underneath my car, passenger side, I had a wire disconnected. It is a black/white wire combo that plugs in underneath the battery. I know the PCM ground is black/white, so is injector #5. Anybody know what this wire is for? Could this have been my problem all along? don't really want to replace opti but will if I have to.
It could be a wheel speed sensor connector. Can you post a picture of what it is?

One single wire? I don't know of anything that plugs in under the battery, but the horns and those wires are green.
The low coolant plug is the only other thing I can think of in the area by the battery. It has a yellow/black and a black wire in the plug.
