The wires goes along side between the carpet and the side plate of the doors all the way to the back up to the hatch.
You will need to drill a hole in the hatch for the wire for the camera. The kit supplied the wire but was to short so you will need to get an extention for the camera.
I am also interested in installing a backup camera on my Toyota Sienna (2004 XLE model). I would like some guidance before I start the project.
I plan on installing the camera on the hatch, at the location where stock cameras normally go.
My desire route for the camera wire is shown in the image below. Since the other end of the camera wire need to be connected to the head unit, I figured running it through the floor is a better option.
Before I start the project, I would like to know how to remove the trims, carpet, molding, etc. properly. I took a temporary subscription to Tech Info Toyota, so I have access to the service manual, collision repair manual, and so on. However, I have not found any specific instructions, yet, as to the proper removal of the trims, carpet, molding, etc. inside the car.
Does anyone have any instructions, suggestions, tips, etc. as to how I can accomplish this? If you have any specific pages or sections on the Sienna '04 service / repair manual that I can refer, please let me know as well, so I can look it up.
