Its pretty simple to install but you must be very careful when doing it. The shrouds that the moniters come with will need to be install nice a snug or you will have problems in the future. Cut the hole/square alittle smaller then the shoud to allow for a tight fit(start small first). The wires can be ran thru the head rest post and down the back of the seat inside of the liner. They have the normal power and ground connections you will have to do. As for the video input, run a Y-spliter to your monitors(if needed). A head rest job is simple to install, just make sure you take your time. You really dont have much room for any mistakes when installing them. Good luck on your project.
