Direct wire harness for Pioneer Headunits (fits 2000-2008 Chevy/GM vehicles- See compatibility information below)

Item Number: AHH-70-2003


AHH-70-2003 AHH-70-2003


This harness is the simplest way to install a Pioneer headunit in your Chevy or GMC vehicle. It is pre-wired with the Pioneer connector on 1 end and the Chevy/GM connector on the other.

Not compatible with amp systems like Bose, Infinity, On-Star etc.

What's included:

  • Pioneer Direct Wire Adapter, AM/FM radio adapter, and 12V power lead (for vehicles that do not have a +12V supply in the OEM radio wiring)
  • Steering Wheel Control wires are provided to the OEM connector (This signal is unique - the signal is not provided on most aftermarket install harnesses) Multiple wires are provided for this and some of them will not be used on all vehicles.
  • Reverse, Vehicle Speed, and E-brake signals are provided from the Pioneer connector since this will need to be connected elsewhere on the vehicle.
  • +12v switched (Red) and Ground (Black) connections are provided for wiring of a steering wheel control interface or other +12v devices.
  • Amp Turn-on signal is provided for connecting a Parking Brake Bypass module


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

This harness will fit any 2014 or newer Pioneer headunit with a video screen.
(If your unit does not have a video screen, slight modification may be necessary. Click here for more details.)
