7.3 main engine wire install

As part of a significant maintenance update on on my 2002 ford excursion, I decided to install a new main engine wire harness. Can anyone refer a good video or instruction on install? I rebuilt fuel bowl, fuel lines, ebpv etc etc. I am in a process of putting it all back together and doing it right (in order) the first time is my preferred method, although it often doesn’t go like that. Thanks to those who recommended the updates!

Are you talking about the top of motor harness?

Just start at the CPS and unplug everything. Lay the new harness in the same location and replug everything.

Its a 20-30 minute job at worst.

ya, I did a bunch of work and took the harness out to have better acces to the valley. I should have taken a picture of the layout and where the lines were run
