Here's a picture of mine but it requires some explanation.
I replaced the stock breaker with two 40 amp breakers wired in what is known as parallel, which means each breaker handles an equal share of the electrical load.
Here's an explanation for the two red wires the come in from the bottom of the box and connect to the breakers. One is a wire directly from the battery, and the other is a jumper wire that runs over the single breaker shown right of the box.
Circuit breakers all have some kind of markings on them to indicate which wire should be connected to which terminal. The word terminal is in reference to the threaded posts sticking out of the breaker. If you look closely at the left breaker in the picture, you can see "AUX" (it's upside down). This indicates that the wire from that terminal goes to whatever the breaker is powering, which in this case is the slide motor. Some breakers will mark a terminal "BAT" or "BATT" which means you hook up the power (the wire from the positive battery post) to that terminal.
The red covering you see on the terminals in my picture is 'Liquid Tape', which is a type of electrical tape applied like thick paint.
Hope this clears things up for you.
