I am trying to install a car alrm into my Blazer and have no idea what wires are what. Also the door lock system is driving me nuts, how to wire it so that it works with the keyless entry?

This wire will be used to control the bypass module, if needed. This wire will require a relay for the Brown (ACC)wire. |

To Lock/Unlock, we recommend use of the 23561 Door Lock Interface module, available through DesignTechs sales department at 800-337-4468 . Alternatively, you can wire inside each door for reverse polarity door locks. The 23561 module is easier to install, less expensive, and requires less wiring than the reverse polarity/relay method. Motor Wires, should you choose the reverse polarity method, are Gray for Lock and Tan for unlock. SOME of these vehicles have a switch on the right rear panel which can lock/unlock all doors as a positive trigger system. If so equipped, the wires are Lt Blue for lock and White for Unlock. Connection of the locks without the module is not supported. |
