It could have helped if you specified a year. Tempo was made from '84 to '94 and changed a considerable amount. Go to: http://www.the12volt.com/installbay/vehiclewiring/1/modeld/Ford.html
Then look for your year and go over to the right side and click the "Stereo" link.
Voila! this site is correct in it's info. I used it for my '92 Tempo GL.
with "ford radio removal tool"
A Ford Tempo will have no brake lights if the bulb has blown or the wires have come loose. Alternatively, the brake sensor in the dash can fail and stop sending power to the lights.
You can get a Ford Fiesta stereo wiring diagram at a website called modifiedlife. It also lists all the wire colors for each component that is needed for wiring the stereo.
