Hi all, great info in this thread. My 1975 SIII 109 has the otter switch (no wire attached), and what appears to be a previously replaced choke cable with no cold start cable switch. The wires behind my cold start dashboard indicator light were cut. Does anyone know if the otter switch and choke cable switch were meant to exist together, or was it either/or? If they were meant to exist together, does anyone know the correct way to wire everything up?

The otter switch and cable switch work together , and are connected in Series. Wiring goes from ignition switch , through the warning light, then the cable switch and finally connected to the otter switch which completes the circuit to ground when the engine up to temp. Both the cable ( Choke operated) and otter ( Engine Warm) switches need to operate to illuminate the light. During the S3 production the otter switch was deleted and just the cable switch retained, which meant the light illuminated whenever the choke operated.Comment
