I have been trying to install a pop & lock power tailgate lock. Everything has gone in fine but the wiring they suggest does not seem to be correct. Does anyone know the colors for *lock* and *pass and rear unlock*. I am a complete newbie messing with electrical. I bought a wiring probe but have been unable to isolate what I need. By the way I have a 2005 screw lariat if that makes any diff. Thanks
