Sounds like you have the switch and motor sides backwards? Might want to double check that..The sides going towards the door are your switch sides and should goto pins 87a on the relays. The other sides going towards the rear of the vehicle would be your motor sides and would go to pin 30. Then of course pins 87 would get constant 12v fused. Is that how you have them wired? Also, might want to double check that the factory wires are still resting at ground instead of resting at 12 volts. Sounds strange, but if you give them the wrong polarity they will switch on you and rest at 12v and activate with a ground..If so you need to hit them with the wrong signal again so they switch back. Definately test first to see if they are still resting at ground like they should, and the switch sides should get 12v when you hit the appropriate lock/unlock button. Good luck, Mike

all superduty trucks without factory keyless have reverse poarity locks with a 12 volt trigger. cut the pink yellow and pink green in the kick. and get your two relays. put pins 87 and 85 on both relays to 12v constant. take pin 87a on one relay and connect it to the pink yellow that is comming from the front of the vehicle . now connect pin 30 to te other side of the pink yellow. now do the same for the other relay on the pink green. pins86 will go to your triggers on your keyless entry, if you wanna test them you can tap them to ground one at a time and watch your locks dance. it is like magic. p.s. i work at a ford dealer so i do an outrageous amount of these
