Thanks for the great writeup, unfortunately things are not going smoothly for me. I have a 2012 F150 supercrew with keypad and rear camera. I followed your instructions, but ran into some odd problems. When i connected the servo mechanism to the Lt Blue w/ Green stripe and Lt Gray w/ Brown stripe the vehicles locks continually unlock or lock. Nothing happens with the servo. I get the exact same result if I simply connect the two wires straight together (without the servo). I did test the servo on the battery - it works fine. Not sure why it reacts as if it is being shorted - any ideas would be helpful!

I tested in the passenger and driver side - same result. The passenger wire had numerous gray/brown wires - again, some result. Not sure if something is wrong with my servo?? how would i test?
