Hey we found a diagram earlier for 2004 Chevy full size truck... some parts were different.
This is the 4 door version.
Having trouble finding the universal door unlock and lock wire along with the open door sensor cable.

The '04 uses data wire for the door locks and you will need to use a doorlock interface module. On base model trucks the door trigger wires are in the lt. blue plug at the BCM, pins B4 and A5. On 4dr trucks the LR door trigger is lt. blue/black, pin A3, and the RR is lt. GREEN/ black, pin A2. They are in the purple plug at the BCM. Use all wires and diode isolate.The BCM is under the driver side dash below the steering wheel
