On the 94 LT1 pcm, is there a specific pin that illuminates the check gauges light on the instrument cluster? I’ve looked in the schematics and have not found it. Although I will have a voltmeter gauge in the car, I’m wondering if I can have the pcm light the gen light on the 79 Malibu dash as well.
I suppose the check gauges light could be lit by other things like low oil pressure or high coolant temp, but those stock LT1 sensors will not be used in this swap. Oil and temp gages will be old school mechanical.
I see the tach out signal pin. Can I use that to signal my old school Autometer tach or do I need to just hook the tach up to the coil as usual?
