97 Ford Explorer Sport, Clifford RSX3.5

I just installed a Clifford Matrix RSX3.5, and it has a wire to arm the factory alarm, however according my cars wiring diagram the only way to arm the factory system is to send a pulse to the door tigger wire and the power lock wire. However when i do this it connects the door trigger wire and the power lock wire, so whenever i open the doors it locks the doors repeatedly until i close them or whenever i manually lock the doors the car says door ajar. I have tried using diodes, which fixes the whole connecting the two wires together problem, but then the factory alarm doesnt arm. (placed two diodes on the wire coming from the new alarm, with the silver band on the side of the new alarm, allowing signal to flow from new alarm only, and connected one diode to the power locks and the other to the door trigger). Has anyone had this problem also, or know how to fix it? I pretty sure it is common in all fords. Any help would be greatly appreciated. Thanks
