I had a rattler 300 installed in my truck at circuit city. When it was installed I didn’t have power locks. When it was installed i didnt have power locks. I converted to power and now I am wondering how to hook it up to my alarm. The power doors locks have a module with 2 wires coming out and it says to hook these up to the alarm.My problem is I don’t know what the pin config is on the alarm.I have tried to get a harness from many places and they always tell me to call DEI so I call them and they tell me to call the places I just did.The wires when I touch them together lock and unlock, it if that helps. Thanks for any input.

The brain of the Rattler has a printed diagram of its outputs right on it.

You could search around for the missing plug, and then wire up two relay to control the actuators. But if you go and buy a DEI 451M, it's essentially two relays built into one little box, it has clear instructions, and it has a plug that'll most likely go right into the Rattler.

451Ms should be dirt-cheap on eBay, or maybe $25 and full retail.

Thanks for the quick response !!!

The brown and wire wires that are coming from the power lock module where do they go on my alarm? The brain on the rattler does have the outputs diagram on it but which ones do i connect the wires to? There are 6.... i can connect the 2 wires from the power lock module to im assuming pins 2 and 3 and it will un-lock on disarm and when i put the wires on pins 4 and 5 it will lock when i arm the alarm.

IF the rattler has a small white plug with a small green and a small blue wite coming off or it you will need to put two relays between your alarm and the motors. The install guide with your alarm should have had door lock diagrams in it. Go to where you bought it and ask for the install guide they probibly took out and kept. Or find a Python dealership and ask for the 650esp install guide it is a must have for reference on relays.
