Why we need to know this All car manufacturers use color coding on their wiring
systems. German cars use red for battery +, black for ignition hot, brown for ground, ect…
Japanese cars use white for battery + and black for ground. Wiring color varies from vehicle to vehicle, but good schematics should include codes for wiring color.
