Well the easiest answer is that if you aren't very familiar with wiring, you should find someone who is to come help you. You're right, you
don't want to burn it down.
You will need to either splice into existing wires, or run a new set of wires to your power center if there's an open space which can be fused. I know my power center isn't really set up to have things easily added to it, so I just spliced into the nearest set of wires I could find in my camper, after figuring out what they were powering, and making sure the fan wouldn't be overloading the circuit.
The wires I found powered the hood fan and
light, and another kitchen
light. Since I had just switched to
LED lights, I figured, after looking at how much power the fan would draw, that with the reduced draw of the LEDs, I'd be ok with my fan in that circuit. You'll need to figure that out too.
