Clark Kent

I am installing a Pioneer F700BT in my car. I am replacing the Shaker 500 unit I have now. I know which harness to get, but I was just wondering if anyone had some detailed instructions as to installing the unit. Like for example how to wire the harness to the HU ( which wires connect to each other) Also if there are any other wired I need to run and where to. What im really asking for is as much information as I can get, so that I dont screw up the install.
