Pioneer DMH 1500NEX Wiring Diagram

The Pioneer DMH 1500NEX includes a wiring harness that is used to connect the head unit i.e., the main control unit of the car stereo to the power supply and the rest of the car’s audio system. However, installing Pioneer DMH 1500NEX can be complex, and it is always a good idea to have it done by a professional.

Pioneer does not recommend you install this head unit yourself. So, if you are not familiar with the Pioneer DMH car stereo manual, it’s best to seek help from authorized service personnel to avoid damaging your device or the car.

Generally, to install this receiver successfully, you’ll first need to identify the purpose of each wire in the car audio system. Car audio color codes are standardized across the board, but some manufacturers can have variations. That said, the Pioneer DMH 1500NEX color codes are;

i. Power leads

  • Yellow – This is basically the battery wire. The cable represents the terminal supplied with battery power irrespective of the ignition switch position.
  • Red – The red cable offers a connection to the terminal controlled by the ignition switch. The ignition wire delivers up to 12V DC (ON/OFF).
  • Black – The black wire represents the ground terminal, and connects to the vehicle’s (metal) body.
  • White/orange – The white/orange cable is for the lighting switch terminal.
  • Violet/white – This lead connects to the back lamp.
  • Yellow/black – If you intend to use the Mute function with your device, you’ll need to wire this lead to the Auto Mute terminal of your device. However, the lead might not be of much use if you don’t plan on muting any device.
  • Blue/white – This is a 12V DC wire that connects to the terminal of the power amp system control.
  • Light green – This lead is used to determine the status (on/off) of the parking brake. The wire is often connected to the parking brake switch.

ii. Speaker leads

  • White – Left front speaker (positive)
  • White/ black stripe – Left front speaker (negative)
  • Gray – Right front speaker (positive)
  • Gray/black stripe – Right front speaker (negative)
  • Green – Left rear speaker (positive)
  • Green/black stripe – Left rear speaker (negative)
  • Violet – Right rear speaker (positive)
  • Violet/black stripe – Right rear speaker (negative)

It is important to remember that this unit should be used with a negative grounding and a constant 12-volt battery only. Failure to adhere to this safety rule will result in malfunction or fire accidents. And to prevent electrical shocks, always ensure to disconnect the battery cable before doing the installation.
