Help needed installing autometer gauges

I need some help hooking gauges to my 95 civic ex. I have autometer a/f ratio, water temp, and voltmeter. I have power and grouds run to the gauges, but I need to know where to run the wires from the gauges to make them work. I know the wires connect to the back of the gauge, but where do the wires run from on the 3 gauges, thanks in advance, Jason.

af is hooked up to o2 wire and volt's well the battery and as far as temp you use the output of the temp. sending unit.
