I am installing the Easyguard EC002-NS PKE Passive Keyless Entry on a friends F250.   I used the list posted here.
I'd previously installed it on two Sequoias and one Tundra without any issue - but I suspect the door (un)lock system is different on the Ford. On my Toyotas, all I had to do was apply positive pulse to one pin to unlock, and positive pulse to another pin to lock.   
However, on the F250, I cannot wrap my head around the mechanism.
Power Lock     Gray/Yellow     -     Door Lock Switch in driver door, 4 pin plug, pin 1 or black 8 pin plug, pin 7
Power Unlock     Violet/Gray     -     Door Lock Switch in driver door, 4 pin plug, pin 3 or black 8 pin plug, pin 8
Lock Motor     Gray/Brown     Reverse     Driver Kick --or-- BCM in passenger kick, 36 pin plug (C), pin 35
Driver Unlock Motor     Blue/Green     Reverse     Driver Kick --or-- BCM in passenger kick, 36 pin plug (C), pin 27
Passenger Unlock Motor     Brown/Green     Reverse     BCM in passenger kick, 36 pin plug (C), pin 32
I did 100% of the installation from the BCM. The friend has a service manual for the truck so I was able to confidently find the correct plugs, pins, and colored wires.
My attempt was to connect o the lock motor (Plug C, pin 35), and the passenger unlock motor (Plug C, pin 32).    Before applying the alarm, I tried to measure the voltage at each pin to ground. Unfortunately, my meter is too slow to pick up the voltage as the factory (un)lock buttons are pushed.
I think my confusion comes from the "REVERSE" polarity description.   Could someone with a bigger brain explain to me how I should attach the Easyguard system? I can configure the outputs to be either positive or negative.   There are NO/NC outputs as well, so I should be able to configure it as required. Just need some hand holding.
