I have created individual schematics of virtually every circuit in all variations of the MGB - hopefully you will find them a little clearer than the official diagrams. If you hover your cursor over a wire it should change shape to indicate a link, and then display a 'tool-tip' to confirm the wire colour.. Get clear MGB 1964-1978 electrical wiring diagrams with step-by-step guidance for restoration, troubleshooting, and classic car projects.
