I wanted to know where the backup sensor wire is inside the cabin of 2005 Frontier Crewcab automatic. I have installed Kenwood DNX7100 and need to tap into the sensor. I didn't want to do it underneath the hood if I don't have to. I don't feel comfortable doing it there is why. If I have to I will. I have soldered and shrink wrapped my connections at the backup light and then threaded the video cable through the back cabin vent but it looks like I have to tap the sensor in order for the radio to use the backup camera. Appreciate any help anyone can provide me. Thanks in advance.
