DETERMININGDOORLOCK TYPE:
Werecommend determining the type oflocking systemthe vehiclehasbeforeconnecting anywires.Incorrectconnection

procedureforcommon doorlocking systemsunder“DOORLOCKSYSTEMSpage 10.
Negative orPositive Trigger(-/+): ManyVehicles:Imports,Ford,GM,Chryslerand European
Negativetriggerdoorlock systemssend aNegative(Ground)pulsetoexisting factoryrelays tolock and unlock the vehicle
doorswhilepositivesystemssend a+12 Voltsignals.

unlock switchesinthe door.The lock and unlock wiresrestatNegativeGround when notinuse.When the lock orunlock
button ispressed,one ofthe circuitsis“Lifted”and replaced with+12Vcausing alock orunlock tooccur.
