You can still do it but you will have to purchase the harnesses. They should be fairly cheap.

Check out these links they have a bunch of great info on the subject:

Hope this helps. Good luck with the install. Make sure you check the main harness at the back of the truck to see if the video wires are run to the back. They are not on my truck so I will have to run my own.
