How to locate an open circuit in a wiring harness

This is a 97 Ford Crown Victoria with a 4.6L engine, that does not start. There is no 5 volt reference and no check engine light. Following the EEC Power relay revealed a missing power feed. Follow me as I find the open in this harness using a new tool.

Tools used
- ECT3000 Circuit Tracer (I used the ECT2000 in this video, maybe the 3000 series will have a more powerful open circuit signal?)
