i have the wire harness but dont know how to or where to hook it up at
Do you have both wiring harnesses that you need? You need one for your car and then one will come with the head unit you buy. If you have the wiring harness for your car and the wiring harness for the radio then you just need to connect the wires with the same colors together.
I don't know right now. Hey, Don't ya hate it when someone takes advantage of your question just to get the points to add up so that they can then start rating other answers? Heheh :-D
