Billy the kid

I’m trying to take a g8 base and swap a 6.0 into. I know it won’t be the same l76 but 6.0 out of a Yukon (don’t know the exact engine code) or something. I’m just wondering if the sensors and harness would be the same because they are both 6.0? Not to many people have done this so I’m hoping some of guys with years of experience could steer me in the right direction.
