The Chevy uses a (+) type B door lock system found at the BCM which is located behind the drivers side of the dash. The plugs on the BCM face towards the rear of the vehicle. If your alarm system has alternating polarity door wires, the attach the ones that pulse (+) to the target wires and your set. If your alarm does not have this option and is only a (-) trigger door lock system you will need to reverse the polarity of the wires to a (+) by using the NEGATIVE INPUT ---------------> POSITIVE OUTPUT diagram below:
