need knowledge please

i have aquired an 05/06 5.7 hemi and know very little to nothing about them. i have 1 in my 08 truck. this one has no wiring harness but other than that is is complete. i bought a book but think it may have been the wrong book. i don't know what all is involved in changing it to carb or anything else. might be in over my head on this. if it was a sb/bb i would not have a problem. i see that there is a swap kit for trucks now. please don't beat me up too bad for my lack of knowledge on 20200818_221311.jpeg the 5.7. haha.
