Installed the 4-40 ring terminals on the ends of the alternator shunt wires from the EMS-220 harness. Added some heat shrink and installed on the shunt. Installed the OLC-1 connectors on the red cube wires after getting another set screw I lost earlier. There is some debate on the security of these connectors so I added some heat shrink and lacing cord to ensure the connection and strain relief. Rerouted the Hall sensor wire through the right firewall penetration and through the 3/4 snake skin to the EMS-220 connector. Did some research figuring out the connection between the Hall sensor and the EMS-220 wires. Strangely the white/orange wire from the connector connects to the white wire from the sensor and the white/orange wire from the sensor connects to the red wire from the red cube. (See dwg) Meanwhile the blue/white wire from the sensor connects to the black wire from the red cube. Seems like that could have been coordinated a little better. I just twisted the wires together until next work session after I determine the best way to splice the appropriate wires together.
