Hi Nick,
I went out and removed the rain hats from the ITB's and took a couple of photos of engine wiring harness.
Harness connector that plugs into the back of the electrical panel in the left rear corner of the engine bay:
Overview shot of the harness from the distributor running diagonally across the engine towards the starter:
This shot shows the wires coming along the cooling fan shroud to the oil temp and oil pressure sending units:
This shot shows the harness connecting to the oil pressure warning light switch and then heading out the back of the engine bay and down to the starter solenoid:
Keep up the DIY spirit!
