My service is cheap, quick, and good - pick any two

I've done a couple, and the colors Chris mentions sounds right. The modules from idatalink.com will give you a lot of time-saving outputs. You won't have to run wires under the hood, or inside the door, and you won't have to give up your valet key. If you do buy one of their modules, it needs a special firmware for that car or it won't work. Make sure whoever you buy from will sell it to you with the correct firmware already in it.
