hi evryone ,
hope all doing well , i did quite some research and couldnt find any specific info , i have a 2015 f150 xl without keyless entry , i installed a remote start ,keyless entry and i am having hard time to find where to connect lock and unlock trigger , i though to the switch of the door pannel ,but those switches does not work too , which wires should i be looking to? BCM module wiring seems complex and hard to understand which wire will trigger lock and unlock

 

This is for a 2016 but I believe it is the same as the 2015.

 

I would hook it up right at the door lock switch. What u want to do is test the wires with a test light & hook up the lock wire to the wire that shows NEGATIVE polarity when the lock button is PRESSED. & hook up the unlock wire to the wire that shows NEGATIVE polarity when the unlock button is PRESSED.

 

thank you for the quick reply , i saw the diagram too , but this will only work if i want to provide voltage directly to the door actuators.my system that i have installed have 2 wires one unlock and one lock wich both give negative polarity when pressed respectively (negative trigger or ground ) .also the door lock switches in my car are connected and illuminated but do not work . (why ?i don't know) .But when i drive the car at a certain speed it will lock all doors and when i put in P and open driver door it will unlock all doors.so seems my system is fine but why my lock/unlock switch do not work i dont know ,would have been too easy to connect it there.any other suggestions?

 

you have a short in one of your door lock wires. Take the drivers door apart & try the switch. Make sure that none of the door lock wires are pinched somewhere.

 

You don't really say what system you are using to try and get the door locks to work other than you have two wires. The door locks in the truck work off the BCM, the switch in the drivers/passenger door is hooked to the DDM/PDM module in the door, then uses the trucks network to communicate to the BCM to unlock/lock the door. The BCM is locking and unlocking the doors when the truck is moving. Other wires are lighting the existing switch. I don't see any inputs for the door locks on the BCM.

 

i did dis-assemble front door driver side all wires seems normal no issues , i dont knowi f its an issue in other side but if there was issues with actuator wiring even BCM wouldnt be able to lock unlock door locks no?

 

that is what i thougt also , long are the days we have dum system where you can tap in anywhere .The modules on the doors communicate with BCM with CAN communication protocol ,so unless you connect in the lock/unlock switch (wich my case they are both not working left or right door) i dont see any where else i can connect . I am using EASYGUARD system EC002PP plug and play kit .most wires are plug and play and through OBD , so i have remote start ,push button all working . Only problem is lock unlock wires , hazards lamp and horn wich i cant seem to find .the most important is lock /Unlock triggers

 

this attached is what i have received from salesteam of easy guard which wires to connect today ,not sure if it will help but if you are familiar with those wire location let me know . i will try this out tomorow

 

They are in the door at the switch, 4 pin plug, that's what my wiring diagram has. As I said above, the door lock switch connects to the DDM module in the door, those wires do not leave the door.
