Direct wire harness for Pioneer Headunits (fits 2001-2015 Mazda - See compatibility information below)

Item Number: AHH-70-7903


Pioneer Direct Wire Harness for Mazda


This harness is the simplest way to install a Pioneer headunit in your Mazda. It is pre-wired with the Pioneer connector on 1 end and the Mazda connector on the other.

What's included:

  • The Vehicle Speed signal is connected (This must be cut for Pioneer units that don't require a vehicle speed input)
  • Steering Wheel Control wires are connected. The Maestro SW connector (this is the white connector in the picture above) is pre-wired and will be plug-and-play once the Maestro unit is configured properly using the iDatalink Maestro web utility.
  • Amp Turn-on/Trigger signal is provided for use with an E-brake bypass or for using an aftermarket amplifier.
  • Reverse and E-brake signals are provided from the Pioneer connector since they will need to be connected elsewhere on the vehicle.
  • Installation instructions are provided with your adapter.


1) Just connect both ends (to the Pioneer and to the Vehicle)
2) Configure the Maestro SW for use with your vehicle. Connect it to the Pioneer unit using the adapter that came with the Maestro SW and Connect the white connector on this harness to the Maestro SW.
2) Connect the E-brake signal (Reverse is needed only if you will be connecting a backup camera)
3) If the Pioneer headunit does not have a GPS antenna, cut the PINK Vehicle Speed Signal wire, which has a tag on it. (This wire is used for a different function on non-navigation Pioneer headunits)
