Only one on my 96. Any extra would be for aftermarket parts not running through the breaker panel such as car alarm, spot lights, winch, etc.

So you have no power at all? Did you make sure your ground is on and tight? In a stock setup you should have only the one power cable from your + and your - will have two the main that's grounded to the engine block and a smaller one leading to your body.

one positive goes to the starter lug, the other goes onto the fender mounted solenoid. the positive cable for the fuse box gets its power from the cable attached to the solenoid.
