You need to diode isolate the pin wires. break the wires at the ECM and put a diode in line with the cathode AWAY from the ECM. Now past those diodes (remember AWAY from the ECM) is were you will grab your triggers now. You will need 2 more diodes. Split the negative trigger input from your alarm, put the diodes one to each (blk/yllw, blk/pink) with the cathode AWAY from your alarm brain. The cathode end is the end with the white line. -------------

So, in total, you used four diodes, right?
Did you actually cut the factory Ford door trigger wires in half as part of your installation?
Somewhere on here there is a diagram of how to do it, which is easier than explaining in text.
