im currently bidding on this:

and im wondering what kind of wiring harness im going to need to hook it up

 

^Whoa, that's cheap... Hopefully it'll last a couple months! The item will come with it's own harness w/ wires to hook up to your factory harness. <-- It'll require splicing wires together. But, "if" you want simple plug-and-play you'll want to get a Mistu wiring harness to attach the two together. You'll still have to attach the harness you get (Best Buy/Circuit City/etc) to the wires on the deck, but it'll then just plug into the factory harness already in the car.

Good luck!
