Lock/Unlock wires `96 Subaru Legacy

you need to add actuator to drivers door in this vehicle for keyless to work.

it already has keyless entry (factory) if thats what you mean? im trying to hook it up to my alarm but i dont know which are the lock and unlock wires under the dash

If you can find the Blue and Red, Lock and Unlock wires coming out of the keyless entry barin you can do it.  I also have a `96 Legacy with keyless entry.  You'll have to set up a two relay lock and unlock rig to get it to work with an aftermarket alarm.  If it is like my `96 there is already an aftermarket actuator in the door.  Aftermarket alarms don;t put out enough juice to get the lock and unlock features to work,  that is the reason for the two relay setup.  Let me know if you need anything else.Richard Bell
