Replacing engine wiring harness, throttle body, and more on the SL320 (R129)

Last time it was mounts, this time it's sparkplugs and the engine wiring harness

1993 - 1995 Mercedes-Benz from the factory had a harness with biodegradable insulation. Some of them were fixed under warranty (if the original owner still had the car). Some have had the harness replaced. Mine is all original. There are 3 areas/harnesses impacted:
engine wiring harness
throttle body
lower wiring harness (not addressed here)

This video shows the following:
Valve cover gaskets replaced (seals around spark plugs leaking)
New spark plugs
Replaced throttle body with ProgRama rebuilt part
Replaced engine wiring harness w/ Delphi rebuilt part
New ignition coils

Did it all work out? Did the car even start after all this? You'll have to watch to find out 🙂

Please note: I'm not a mechanic. Working on cars is a hobby that I do in my free time. Apologies in advance for messing up any terminology, etc.
