I am installing an air/fuel guage in my 95 and have run across a slight problem. The directions with my guage do not specify, nor can I locate it in the Hayes manual, which of the 4 O2 wires I need to use for my guage. It should be the 0-1V wire. With my voltmeter, I have narrowed it down to 2 wires, but do not know which is the heater and which is the signal. Any help appreciated.
