Short Description: Wiring Labelling, Termination And Connection.

Today was a long and tedious day working on several of the EMS wire harness sub-segments for items behind and under the insturment panel on the cabin side of the firewall.
Pulled the wires from the EMS DSub 25 pin connector to label and terminate them for the following components:
1) Under-panel CO detector.
2) Gold Cube fuel flow transducer (also sheathed).
3) RED capacitance fuel quantity probe.
4) Pitot heat signal line (called out in latest manual to go to EMS pin 9 rather than ACM AIRCRAFT REAR DSub connector if installing on a SkyView system).
Also terminated the capacatance fuel quantity probe's grouns line. Both the probe and the probe controller box had to be grounded to the same ground point.
Ohmed-out all cable segments between EMS DSub 25 pin and the final terminal connector to verify all crimps from the pin to harness end were good.
Connected all components to there respective EMS DSub 25 sub-segment harness and temporarily tucked the service loops.
