I have a 96 ES300 and i'm trying to install an aftermarket alarm. I installed this alarm on my Talon and it worked great so I know I can do it, but I can't find the door lock/unlock wires. It says on the diagram that they are yellow/blue and yellow/red and can be found in the pass. kick panel or the theft ecu. I found the wires, but when i tested them they both showed constant ground all the time, even when you lock and unlock the doors. I am really confused and any help would be very appreciated. TIA guys.
