I need the engine wiring diagram for 2007 yukon 2wd 5.3l

[tabwal1992]

Please help my 2007 yukon has had many electrical issues, I started looking at the wiring harness and the connectors under the fuse box was horrible and I believe it's not the right type of fuse box I've had to change my fuse block 3 times since I've had my truck and when I went to look at the connectors it was horrible some of them had got glitter glue where someone tried holding them in. So I began researching it and discovered a new wiring harness would be expensive to replace. The wiring is chaotic none of the wiring is covered everything is just lose wires everywhere. So I was thinking I could just get new connectors and change the pins out but nownincant find the diagram for the connectors on the bottom of the fuse box. Can someone please help me out cause I'm lost from here
