I've got an 5.3 out of an 06 Rainier for a swap. I've got the ECM, the BCM that is attached to the rear fuse block and the lift gate module. The DIC is part of the instrument cluster which I didn't pull. According to the owners manual you can program things like having the headlights stay on for x or xx etc seconds after the car is shut off, control if they flash when the remote unlock is used and other features. In the Rainier they are programmed by way of the DIC.

Anyone know if this stuff is stored in the ECM, BCM, cluster or where and if it is possible to program these types of features without the cluster?

Thanks
