I would not go cheap on this part. I have put in 3 different ones I used a cheap extension wire it gave a poor quality picture on that camera. These are a fair amount of work to put in. i would search a camera that gets good current reviews also look at comments with someone who has had the camera for while as they can go bad. I have used Crutchfield.com they have a varity of prices they also price match and have good tech support.
