If you are installing an ATOTO A6 PF model, please click here to go to the correct page. The Wiring Connector shown here will not fit the ATOTO A6 PF!

This harness is the simplest way to install an ATOTO headunit in your Honda or Acura. It is pre-wired with the ATOTO connector on 1 end and the Honda connector on the other.

What's included:

  • Steering Wheel Control signals are wired for you. You won't need an interface like the AXXESS ASWC-1! All that you'll need to do is program the steering wheel buttons using the ATOTO on-screen interface!
  • Reverse signal is provided from the ATOTO connector. This will need to be connected to the vehicle if you are using a backup camera.
  • E-brake signal is already connected to ground to bypass parking brake lockout.
  • AM/FM turn-on wire is included for vehicles that have the BLUE AM/FM antenna power wire (this wire powers the AM/FM amplifier if the car is equipt)


1) Just connect both ends (to the ATOTO and to the Vehicle)
2) Connect the Reverse signals if needed (Reverse is needed only if you will be connecting a backup camera)
