Default 4.8 to 6.0

I've searched the internet for days and am still unsure.

I have a gen 3 lq4 long block I want to replace my 4.8 with. The 4.8 has the dbw throttle body.

The 6.0 has no harness, computer, or pedal. How can I make this happen? If I stay dbw can I reuse my stock pedal?

Is the 4.8 in a running vehicle now?

Pull 4.8 long block out, install 6.0 long block in its place.

I understand that, I'm just wondering if the wire harness and dbw gas pedal is reusable?

Just use everything that was on the 4.8 (harness, intake, etc) on the 6.0

Re-use throttle body off the 4.8 since its drive by wire. Obviously retune for this engine.
