Found a digital outside temp gauge and sender at the pick n pull on a 91 244 and grabbed it. Does anyone know the correct wiring for this accessory gauge? There are a total of five wires, two green which go to the sensor, and also an orange wire, a yellow wire, and a black wire. My guess is that the orange, yellow and black are for constant +, switched +, and ground. Looks like there is a hole for a light bulb too, but I didn't find the bulb holder on the donor. (Someone had already ripped the dash apart on the car and the guage was thrown on the floor.)

Thanks
