PLEASE HELP...

I have a 1987 2.3-16 w/ 219K miles. Recently, the gas, oil pres, oil temp, water pres, and volt meter gauge ceased to work. Along w/ gauges, the brake lights and reverse lights do not work. the driving lights (contants) and signals are still functional--as are the tach, speedo, and econo gauges. All the fuses and bulbs check out. I hesitate to ask this, but is there a simple resolution for this issue (like a faulty relay)?
