12-Volt Power Supply Wiring

• The 1987 Accord's radio requires two power supplies. One power supply provides a constant flow of 12 volts to the radio. This power retains the radio's preset stations, as well as the time setting on the clock. The power is supplied via a white wire with a yellow stripe. The wire runs into the under-hood fuse box and the No. 11 fuse protects the circuit.
  
  The second source of power for the 1987 Accord's radio is the one that turns the radio on and off. A yellow wire with a red stripe provides 12 volts of electricity to the radio when you start the Accord or turn the ignition to the "Acc" position.
