The negative battery cable in a 1994 Toyota 4Runner travels from the negative battery terminal down to the frame of the truck where it is secured with a metric steel bolt. As time passes, this cable can become corroded and frayed. Bare or frayed spots on the negative battery cable can result in poor conductivity and shorting to ground. Replacement negative battery cables are available from most auto-parts stores and certified Toyota dealerships.
