engine swap computer/wiring?

Hello everybody,
I recently bought an 04 4.8l vortec out of a tahoe and am going to put it in my jeep. My question is if the computer out of a 5.3l vortec will work. I know the 4.8 and 5.3 share the same block. I need the computer and a wiring harness. Would these have to come from an 04 as well? I was also wondering if you guys know if you can change the fly-by-wire throttle body to a drive-by-cable, like the earlier 99-02 vortecs. any information would be appreciated thanks.

fuel maps are going to be different for each motor. Buy the correct harness and computer for your motor. Don't pinch pennies on your swap. You will save money by buying the correct products the first time.
