2013 Vehicle Alarm Wiring Questions.

The positive and negative trigger is referring to the type of system the vehicle uses. For example, when you press the lock button, is a positive signal sent to the actuator, or negative (ground). I don't know which system we have, I'm sure a quick google search will tell you.

The ACC signal is any switched 12v signal, when the key is in the accessory position.

Honestly, I'd get a professional to do this job, there are many variables with today's vehicles (transponder keys), that might interfere with this system. I'm new to the Fords, but I do have electronic experience.

Hi All,

I purchased a GPS Tracker/Alarm System for my 2013 SCREW.

I am looking for help on wiring this up. I have not received the thing yet(shipped from china) but I am trying to plan my installation.

I cannot find an online manual for the GPS107 but I found a wiring diagram. I'll hopefully have more info when I get the alarm.

I know that there are not too many specifics about the wiring but I would like to know a few things.

Can someone explain the "possible" meaning of:
(+) Door Trigger

a positive door trigger is a system where when the door is opened, it will complete the circuit sending power to the bcm
(+) FootBrake Trigger

this is the wire that shows 12 volts when the foot brake is depressed and shows nothing (or ground) when the brake is released
Am I looking for a connection that would be made hot when activated? Like the dome light or brakelight

I guess this is a grounded connection, like to a N.O. pin switch(or a pin switch that is grounded(closed) when depressed):
(-) Door Trigger
(-) GripBrake Trigger
(-) Bonnet Trigger


First:
How would I wire this thing to be able to cut the engine. I don't think turning off the oil pump is the best way. Assuming I could use a N.O. or N.C. relay how should I wire this???

most alarm systems have a starter kill. this is a relay inline preventing the vehicle from starting when the alarm is active. the relay is usually activated with a "ground when armed" wire from the aftermarket alarm
Second:
Where would I need to hook up the ACC wire?

accessory can be found in the ignition harness. it is a purple/green wire
Third:
Which "Door Trigger"... The positive(+) or Negative(-) and where would I hook it up?

the door trigger on these trucks is a negative trigger. and each door is pinned seperately. this means you must find each door wire an diode isolate to keep from signal backfeeding. the only positive door trigger is the dome supervision wire. the issue with this wire is that on some vehicles it will not send signal if the dome light is set to off.

And Lastly:
I would like to be able to use the remote lock system so I can lock the truck remotely by SMS also. I have attached the "central locking system" diagram below as well.

you will need to find the lock and unlock wires in the vehicle. there are the motor wires and then there are the signal wires. the motor wires go directly to the door locks and is a 5 wire reverse polarity setup. the signal wires send a negative signal to the bcm which tells the bcm to lock all the doors. these are the wires you will need.
I'll accept the fact that there is not enough information to give the perfect answer but again... I am just looking for planning.

Thanks to all who respond!!

there is a module called the dball and the dball2. these are specific to directed products (viper, clifford, avital, rattler, python, etc...) this module can also work in whats call wire to wire mode. this will allow you to connect to the system through the canbus system which can control the door locks, door triggers, and is necessary when adding remote start. the key to the truck contains a microchip and the dball(2) learns the key code to allow for remote start when the key is not present. this does take both keys to program, but it is the only way to program remote start. unless you use a module like the 556u which requires you put a key in the module and bury it in the dash. this is not a simple project and will take quite a bit of time to complete. be prepared to have your truck apart for quite some time.

peepsnet - I don't have time to go through all the wires and/or circuits you're requesting, but if you send me your email address I can email you the wiring diagrams for all the BCM connectors.
