Hi, I installed water temp, oil pressure, and ammeter gauges in my 71 Grande tonight. I went to install the illumination wires for the gauges by splicing into the air conditioning and heater control box light so that way I can dim the gauges with the dimmer switch. The gauges would not light up at all. I tried switch my ground I was using to several different locations and no luck. Is the wire that supplies that bulb supplying enough voltage to power those gauges lights? Where do you guys wire yours into?
