I think intuitively you need to disable the factory amp first, then add your own amp. As for the wiring harness, you can find them online pretty easy. Check crutchfield.com, you might find it them there, I know I did. Hope it helps

You have to buy the wiring harness and you will have to bypass the amp thats already in it. This is done by basically just unplugging it and plugging in your new wiring harness. Fairly simple task.
