Next came splitting up the Harness.
This gives you an idea of the mess.
I spent a lot of time just undoing the shitty taping that came from factory.
Next, I laid the harness over to see how far the wires reach.
To clean up the mess. I taped the Oxygen sensor, and Oil pressure sender wires separately as if creating a harness for each component. Also there was enough wire to run the through the back of the engine.
