Question about Code Alarm 1100 Vehicle Security System 1100
When installing a security system you definitely want to use the door trigger wires. Now, on GM trucks (depending on the year) you may have to go into the individual doors for the individual trigger wires. The individual door trigger wires on the newer GM trucks (2007+) can be found at the body control module (BCM), located under the dash, to the left of the steering column; left front door is gray/black, right front door is tan/white, left rear door is lt.blue/black and the right rear door is lt.green/black. All of these wires are negative trigger and located in the pink plug at the BCM. Be sure to diode isolate the door trigger wires. The other option is to use the dome supervision wire because in the GM trucks from 2003 to 2006 the wires are in the door. The dome supervision wire is gray/black located at the BCM below the steering column in the black plug.
The above picture is of the door trigger wires for a 2002 Chevy Silverado.Tan for the drivers door and orange for the passenger door in the purple plug or blue/white in the lt.blue plug. I hope that this information helps.
