Doing a little research all the injectors are 25326903 which comes back for a 5.3L L59 Vin Z, flex fuel and the pcm is: 12576106 for 2003 Vortec Truck.
Now time to find a stand alone harness that will work with it.

Looks like you will need a harness with EV6 connectors for the injectors. Your PCM should be a Red/Blue connector and work with a DBC set up. If you are running a 4l60e trans, this harness will work for you, use just need to message them for the EV6 connectors:

If you are using a 4l80e this one will work for your application, again will need to message them about the EV6 connectors:
