Like every one was saying..easy. Just be careful not to break the trim piece..expensive replacement just for the piece..I found out the hard way and snapped one side in half on a install. If you bought a harness, (I am guessing you did just from the way you asked about color matching) The aftermarket should have eveything decoded on the wire, and all you have to do is open the instructions and find the wiring page. Then just match, crimp and go. Make sure all your ends are in tight test your unit, then elec. tape the wires...BAM, your done and there is no chance for shorts, and it is easy for removal if you ever have to...
