Are you refering to the factory keyless entry location and you are looking to install an aftermarket alarm?

I believe the keyless in that vehicle is in the door. The gold delux this is aftermarket right? If so you dont really need to locate the factory keyless module you will need the lock and unlock wires from there but thats about it

no sir gold delux is a alarm made by code upgrade for ford cars and trucks new power code version is simply change daughter board aka dna what i'm trying to figure out is the location of entry which you told me inside door  now if this entry is a new power code system depending i might not have to remove whole system to install my gold system they used the same wiring harrness it never change i would just have to a wiring harrness to complete upgrade with a new daughter board which i have already so i have to remove my door panel check that part number and see what i have

I think Chad is right. Are you locking to add a remote start or just the security? I use to install the dealer add "factory alarm" and a ford dealer. And it was only a swap and plug in to the harness that is add at the dealer.... they don't come from the plant like that. And you will need to leave the factory keyless module in the door.

im assuming you have a LS model grand marquis   which came with factory keyless entry   the kit you are trying to install is a ford add on kit which must be wired into the car the module inside the door is the door module and must not be removed   if you have a GS model marquis (which doesnt have a door module inside the door) then you probley have an add on kit already in it   if it is the add on ford system then you can change the DNA chip but depending on the previous install all the wires may not be hooked up
