I am attempting to wire 3 Autometer gauges. I have been told the following:
To power the gauges, you want to find the Ignition (RUN) circuit. Which means that circuit always has +12V on it when the engine is running. You don't want to use the Ignition (RUN/ACC'Y) circuit because the gauges will be on (draining your battery) if you put the key in the accessory position counter-clockwise position (like when you're listening to the radio). Also, you don't want to use the Ignition (START/CRANK) as this circuit only has +12V when your starting/cranking the engine, but then goes away when the key goes back to the RUN position. As far as the backlighting, you can find any DIMMER circuit (also available on the instrument cluster)
With that being said, below is a picture of the wiring from my FSM. Is IGNITION the RUN circuit and IGNITION-2 the START/CRANK circuit?
Would I want to splice into the IGINITON wire or would I want to splice into something like the OIL or BRAKE lamp wire on the instrument cluster?
