We’ve had a few people asking us about the instrument panel connections on their post October 1969 Citroen DS or Citroen ID, so I’ve written this post to help you find the information easier.
A = Instrumentation illumination
B = + ignition feed for warning lamps
C = Fuel gauge (to tank unit)
D = – Earth
E = Tachometer (rev counter)
F = Temperature gauge (if fitted), to sensor on engine.
A = Main beam warning lamp (blue)
B = Dipped beam warning lamp (green)
C = Rear screen heater warning lamp
D = Hydraulic pressure warning lamp
E = Alternator (charging) warning lamp
F = Empty
A = Left indicator warning lamp
B = Engine oil pressure warning lamp
C = Brake pad wear warning lamp
D = Right indicator warning lamp
E = Hazard warning light (bottom middle red light)
F = Coolant temperature warning lamp
Items such as coolant temperature gauge and hazard lights are not fitted to all models, but the circuits already exist in the instrument panel so it is just a matter of connecting to the appropriate terminal should you wish to add these features to a car without.
