Im trying to install an alarm on a 2004 chevy truck and i need the door lock/unlock wire colors. I tried the lt. blue and white wires at the BCM and that didn't work, do I HAVE to have a door lock interface module or is there a way around it? Any help would be appreciated.

I'll share my limited knowledge with anyone who can use it, and many thanks to those who share their knowledge with me.

You need and interface module for the door locks. Unless you have a base model truck. This is from directechs "On base model trucks, the interface module is not necessary. Instead, the lock wire is lt. blue (-), pin B5, and the unlock wire is white (-), pin B10. They are in the lt. blue plug at the BCM." Hope that helps you out.
