Tonight, I got busy working on the engine wiring harness. When I did the CIS to ITB EFI conversion, I removed no longer needed CIS components: warm up regulator, warm up regulator relay, cold start thermo switch, cold start valve, throttle switch. Since I had chosen x-faktory's Option 2 (EFI + ECU control of ignition timing advance), I also removed the factory CDI module. In addition, several years back Ralf at Don's Autowerks had installed a new higher output alternator with an integrated voltage regulator and had removed the original discrete voltage regulator. That said I cut and hacked on the engine wiring harness leaving no longer needed wires in the harness.
With the engine and transmission removed, I now have full access to the engine wiring harness so I could finally "clean up" the wiring.

Engine wiring harness unwrapped:
Next, I dis-assembled the 14 pin wiring connector that connects the engine wiring harness to the electrical panel in the left rear corner of the engine bay. I made a diagram of the wire colors by connector pocket. Then I removed no longer needed wires from the wiring harness and the wiring connector:
Then I carefully re-populated the wiring connector and began re-taping the wiring harness. I only got partially done when a I ran out of black vinyl electrical tape:
Once I get more electrical tape and some plastic corrugated wire sheathing, I can finish wrapping and preparing the engine wiring harness for the engine / transmission installation. The plastic corrugated wire sheathing will replace the original wire sheathing for the wires that run down out of the engine bay to the starter and to the reverse light switch at the back of the transmission next to the speedometer cable connection.
BTW, collecting more essential supplies for the engine re-assembly:
