Default using truck engine harness?

i picked up a 5.3L truck engine complete with all the wiring. everything on the engine is plugged in. and the tranny wiring is looped up and tied on he back.
this wiring looks to be for the engine only, no other wires, nothing cut and has the 2 plug ins for the PCM. so putting this in my nova, would it work? and would i need any other wiring? what is different about the truck wiring and LS1 wiring? and the 2 plug ins should plug right into the LS1 PCM and work?
would wiring in an OBD port be the only thing i'd have to do?

My project- 72 nova 4-link chassis car street/strip single turbo LS1 (5.3 for now) daily driver.

The truck wiring will work. I believe the only thing you will have to change is the injector connectors. You may have to lengthen an alternator connection or two.
