Battery Confusion
I bought a new battery for my 1991 Bronco. Unfortunately, I did not pay attention to what side the was positive and what side was negative when I removed the old battery. The truck was rewired so all of the battery cables are black.
I think the negative cable is the one that has a bolt going through it below the engine. But, what is the other wire hooked on to the end of the cable (a ground for the trailer package?)
Please let me know if the positive is on the driver or passenger side of the car.
