Wiring Diagram for Pioneer AVH
Now that we know the components of Pioneer AVH, let’s take a look at the wiring diagram. The diagram below shows the standard wiring for a double-DIN Pioneer AVH receiver:
Power Connections
The power connections are the most critical part of the wiring diagram. If you don’t connect the power wires correctly, your Pioneer AVH receiver will not function correctly, or worse, it could cause damage to your car’s electrical system. Here are the power connections:
- Yellow wire: Connect this wire to the car’s constant power source. This wire provides power to the receiver even when the car’s ignition is turned off.
- Red wire: Connect this wire to the car’s accessory power source. This wire provides power to the receiver when the car’s ignition is turned on.
- Black wire: Connect this wire to the car’s ground. This wire completes the electrical circuit and provides a path for the current to flow.
Speaker Connections
After you have connected the power wires, the next step is to connect the speaker wires. Pioneer AVH receivers support up to four speakers, and you need to connect each speaker wire to the corresponding terminal. Here are the speaker connections:
- White wire: Connect this wire to the left front speaker positive terminal.
- White/black wire: Connect this wire to the left front speaker negative terminal.
- Gray wire: Connect this wire to the right front speaker positive terminal.
- Gray/black wire: Connect this wire to the right front speaker negative terminal.
- Green wire: Connect this wire to the left rear speaker positive terminal.
- Green/black wire: Connect this wire to the left rear speaker negative terminal.
- Purple wire: Connect this wire to the right rear speaker positive terminal.
- Purple/black wire: Connect this wire to the right rear speaker negative terminal.
Parking Brake Wire Connection
The parking brake wire is a safety feature that prevents the driver from watching videos while driving. You need to connect this wire to the car’s parking brake system, so the receiver can detect when the car is parked. Here is the parking brake wire connection:
- Light green wire: Connect this wire to the parking brake system. Some cars have a dedicated parking brake wire; if your car doesn’t have one, you can connect it to the ground wire instead.
Backup Camera Input Connection
The backup camera input is an optional feature that allows you to connect a backup camera to the receiver unit. If your car doesn’t have a backup camera, you can skip this connection. Here is the backup camera input connection:
- Orange/white wire: Connect this wire to the backup camera input. Some cameras have a dedicated wire for this purpose; check the camera’s manual for details.
Frequently Asked Questions
Why is the parking brake wire necessary?
The parking brake wire is a safety feature that prevents the driver from watching videos while driving. When the receiver detects that the parking brake is engaged, it allows video playback. If the parking brake is disengaged, the receiver will stop playing video to prevent distracted driving.
What if I don’t have a backup camera?
If your car doesn’t have a backup camera, you can skip the backup camera input connection. However, if you decide to install a camera later, you need to connect it to the receiver unit using the orange/white wire.
