MAZDA RADIO WIRING HARNESSES

Mazda Radio Wiring Harnesses

Every auto manufacturer uses a (+) positive electric signal from the radio to the power antenna, EXCEPT Mazda 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 the power antenna would raise. When the radio or the vehicle was turned off, the electric signal would stop and the power antenna would lower. In order for a new replacement radio to activate a Mazda power antenna up to 1992, a SPDT relay must be used. See diagram below.

using an optional snap on wire harness adapter will simplify the wiring. Most snap on wire harness adapters have already converted and color coded the 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 another reason to use a snap on wire harness adapter.
