Reconnected the turbo wastegate control cable to the servo mounted on the firewall. Next, I began to look at wiring the alternator to the voltage regulator. At this point, I realized that Gulf Coast Avionics had not provided any of the necessary wiring, switches or lamp on the instrument panel. CRAP! I'll have to go back and install all that on the panel and run the necessary wires through the firewall to the voltage regulator.
