Note: using an optional snap on wire harness adapter will simplify the wiring. Most snap on wire harness adapters have already converted and color codedthe wires from the auto makers in dash wire harness to match typical aftermarket radio wire colors.

** The wire colors listed in the chart above are typical for these vehicles during these years but may not be the exact colors for this vehicle. This is anotherreason to use a snap on wire harness adapter. **

Power Antenna Wire from thenew replacement radio

Negative or Groundconnection

Negative or Ground wire connection

No wire connectedto this contact

Convert A (+) Positive Voltage Wire To A (-) Negative Voltage Or Ground Wire

Application: To convert Mazda power antennas up to 1992 to work with new replacement radiosUnderstand: A (+)12 Volt wire connected to the inductor coil (85 or 86) will switch the relay to connect a (-) negative wire to the output contact (from87 to 30)

86

85

87 87a

30

Output Wire going toMazda power antenna

When the radio turns on, the (+) 12 Volt power antenna wire will turn on the relay, moving the contact arm from pin 87a to the (-) negative ground wireattached to pin 87 which is also in contact with pin 30 which is connected to the Mazda power antenna.

Relay Contact Connections

30: (-) Output from relay to Mazda power antenna87: (-) Negative or ground wire

connected to relay86: Power antenna wire from new replacement

radio85: (-) Negative or ground wire

For best results and quicker installation, use thesame (-) negative or ground wire for both 85 and 87

INSTALLATION NOTE:For vehicles with power antennas

Every auto manufacturer uses a (+) positive electricsignal from the radio to the power antenna, EXCEPTMazda up to 1992. Mazda, instead, used a (-)negative electric signal to trigger the power antenna.When the radio turned on, the radio would send a (-)negative electric signal to the power antenna and thepower antenna would raise. When the radio or thevehicle was turned off, the electric signal would stopand the power antenna would lower. In order for anew replacement radio to activate a Mazda powerantenna up to 1992, a SPDT relay must be used. Seediagram below.
