Update:
Massive rewire in process. Removing wires that aren't needed and running new wires where necessary. Still trying to find a good wiring diagram so I can sort out the fuse box.

Turns out there is an unused hole directly behind the driver's side cylinder head that is just about perfect match for my engine harness grommet.

Very happy about that as the engine harness will basically "disappear" once the fuel rail covers are installed. Inside the car, the harness will be just to the left of the HVAC housing and is accessible.
