2000 pcm compatibility with 04 engine

1st time post so i hope its in the right place. Getting ready to start my swap and what i have is a 2004 5.3 out of a tahoe thats dbw. Full harness with it but no pcm or pedal.

I also have an intake, dbc throttle body, pcm and mostly complete harness from a 2000 yukon.

Wondering what my best course of action is. Should i strip the DBC TB wiring from the 2000 harness and add it to the 04 or should i get a dbw pedal and find a pcm somewhere else.

For reference this will mate to a th350 for the time being and is going in a 1970 monte carlo

Thanks in advance for all your help.

You posted this twice. Go to the lower right of the post, hit "edit", and go from there.
