You Can't Hold No Groove

Okay, so i got a question about this song real quick.
Lemme break it down for ya,
i can do the whole thin up to the part with the harmonics. I got the tabs and what it shows is like physically impossible to play and I've tried figuring it out myself on how to make it sound like it does but I can't.
Can someone tell me how to play to play that one part with the harmonics?

 

the only tabs they have are in powertba or guitar pro but ill give it a whirl.

its like this
AH AH AH AH AH
|--24-----12--12| |-12--12--12----------------|
|--24-----12--12| |-12--12--12-----5--5-5-----|
|---------12---7| |--7---7---7--5-7--7-----7--|
|3/22--7--7----8| |--8---8---8----------------|

 

apaprently those "AH's" didnt work out right but those are artificial harmonics on the chrods with the 24 on the g string and everything with 12 on all the chords with the 12 on the g
