Note 1: 1968 and 1969 cars had the pre-engaged starter but no starter relay, the White/Red went direct to the solenoid.

Note 2: There is a bullet connector in the white/red between the ignition switch and the starter solenoid (68 and 69 models) or the relay (70 and later) on all Mk2 CB cars, which is where the transmission safety switch/starter inhibitor wires are connected when the automatic gearbox is fitted. Arrowed below, just above the bracket for the clutch pipe and hose, in the tail that leads down to the starter:

See here for more info on the combined inhibitor and reversing light switch.

Note 3: 1973 and 1974 North American cars with the Sequential Seat-belt System (aka 'bum detector') have the white/red connected to pin 1 of the control unit and a Yellow/Pink from pin 3 of the control unit to the starter relay.
