I am trying to connect the door locks on a 1994 Ford F150, and cannot seem to get it to work. I have tried connecting the positive trigger from the alarm through 2 relays, similar to the 5 wire alternating system, but it does not seem to work. The relays will click, but the door locks wont move. Does anybody have any suggestions on how to get this working? Any help would be appreciated

ford uses reverse polarity locks so you have to cut the wires and reverse the polarity thru relays

So does this mean that the signal wires (pink/green and pink / YELLOW) need to be switched to ground in order to lock/unlock? Thanks again

does the vehicle have factory keyless entry? if not here is what you do... cut the pink yellow and pink green get two relays pin 87 and 85 go to 12 volt pin 30 goes to the side of the wires that shows ground pin 87a goues to the other side of that cut wire. do the same for the other lock or unlock wire. to test tap pin 86 to ground and the actuator will either lock or unlock. connct that (pin 86) to the negative lock or unlock trigger on the alarm.
