When hooking up the wireless back up monitor, you need to wire it into the same place you wired in the camera. (rear back up light) Pick up truck is to long for the wireless signal to be strong enough to keep the monitor on continuously when in reverse. I would recommend this product if using in a regular passenger car. The hook up is easy enough to do if you have a basic knowledge of electric. The directions are ok other than they forgot to add that you need to run the plus side of the monitor wire to the same plus wire you connected your camera to. (otherwise your monitor will flash from time to time while driving.) Do not buy this wireless if you are going to use it in a pick up. Monitor will work only intermittently.
