Bugeye Wiring. The original wiring on an unmodified car was marginal with a generator and only 2 fuses. The lights are problematic due to the ground connections that are strung together with bullet connectors. Then add an electric fuel pump and higher power lights and it gets more fun.

Bugeye Wiring • The original wiring on an unmodified car was marginal with a generator and only 2 fuses. The lights are problematic due to the ground connections that are strung together with bullet connectors. Then add an electric fuel pump and higher power lights and it gets more fun. • The main upgrades I have planned are relays for the high current devices and convert to alternator charging. I broke the system into 6 main circuits that are each fused: • Headlights • Brake lights • Horn • Accessories • Parking Lights • Flashers • Gauge Lights • Wipers • Heater • Tach • Fuel Gauge • Ignition/Fuel pump • Power Port • The following page shows a state table that defines what should be powered for each combination of the key switch and light switch. Each state is controlled by relays.
