Sorry guys I'm 16 and finaly bought my first truck The slow v6 needs to go and I have found multiple engines That is why there is multiple posts about different engines but I found the cleanest and least miles. It is an 07 nbs 5.3 with d.o.d it is complete intake to oil pan then realized it doesn't have accessories or harness so what should I do thanks

You need to read the stickies. You need to read through my old threads. My truck was a V6, and except for yours being an auto, the swap will be the EXACT same
