The unit has two rear USB inputs (often extended via cables to a glove box). These are standard Type A female to proprietary Pioneer connector. Do not cut these; they are data lines. Replacement cables are available online.
This is the "lifeline" of the radio. Incorrect wiring here will blow fuses or drain your battery.
| Pin | Wire Color | Function | Installer Note | | :--- | :--- | :--- | :--- | | 1 | Yellow | Battery (+12V constant) | Connect directly to battery or factory constant 12V. Minimum 15A fuse. | | 2 | Red | Accessory (Switched 12V) | Turns on with ignition. If using a universal harness, tap a fuse like "CIG" (cigarette lighter). | | 3 | Orange/White | Illumination (Dimmer) | Connects to car’s dash light circuit. Lowers screen brightness at night. Not mandatory. | | 4 | Blue/White | Remote Turn-On (Amp) | Sends 12V to aftermarket amplifiers and power antennas. 300mA max. | | 5 | Blue | Power Antenna | Use only for motorized antennas. For amps, use the Blue/White wire. | | 6 | Black | Chassis Ground | Sand down paint at the grounding point. Bad ground = alternator whine. | | 7 | White | Front Left (+) | Speaker positive | | 8 | White/Black | Front Left (-) | Speaker negative | | 9 | Gray | Front Right (+) | | | 10 | Gray/Black | Front Right (-) | | | 11 | Green | Rear Left (+) | | | 12 | Green/Black | Rear Left (-) | | | 13 | Purple | Rear Right (+) | | | 14 | Purple/Black | Rear Right (-) | | | 15 | Brown | Mute | Not used in most cars. Connects to hands-free systems in older vehicles. | | 16 | N/A | Not used | |
Warning: Do not confuse the Blue (pin 5) and Blue/White (pin 4). Reversing them can blow the internal power antenna fuse. Pioneer Avh X3600bhs Wiring Harness Diagram
Pioneer uses a standard color code across most of their aftermarket radios. Here is the pin-by-pin breakdown of the 16-pin rectangular connector.
| Pin | Wire Color | Function | Details | | :--- | :--- | :--- | :--- | | 1 | Yellow | Constant 12V (Battery) | Provides memory for presets, clock, and settings. Must be connected at all times. | | 2 | Red | Switched 12V (Accessory/Ignition) | Turns the radio on/off with the car key. | | 3 | Orange/White | Illumination | Dims the screen when your car’s headlights are on. (Not dimmer—works with 12V). | | 4 | Blue/White | Remote Turn-On (Amp/ANT) | Amplifier turn-on lead (12V output when radio is on). Max 300mA. | | 5 | Blue | Power Antenna | For motorized antennas. Rarely used with fixed antennas. | | 6 | Black | Chassis Ground | Connect to bare, unpainted metal in your dash. | | 7 | Brown | Mute | For hands-free kits. (Often left unused). | | 8 | N/A | Empty | | | 9 | White | Front Left (+) Speaker | | | 10 | White/Black | Front Left (-) Speaker | | | 11 | Gray | Front Right (+) Speaker | | | 12 | Gray/Black | Front Right (-) Speaker | | | 13 | Green | Rear Left (+) Speaker | | | 14 | Green/Black | Rear Left (-) Speaker | | | 15 | Purple | Rear Right (+) Speaker | | | 16 | Purple/Black | Rear Right (-) Speaker | |
Crucial Note: The Blue/White wire is often confused with the solid Blue. The unit has two rear USB inputs (often
Pioneer uses standard ISO color coding for speakers. Note: The striped wire is always the Negative (-).

Below is the official pinout. The main 16-pin block handles power, speakers, and basic controls. The smaller 24-pin block handles auxiliary audio/video, camera, and steering wheel controls. This is the "lifeline" of the radio
The AVH-X3600BHS is compatible with steering wheel audio controls (volume, seek, mode) but not directly. You must buy an interface module. Popular choices:
These modules connect to your car’s data network (CAN bus) or analog resistance wires and convert signals to what Pioneer understands.
The Pioneer AVH-X3600BHS is a feature-rich double-DIN DVD receiver with Bluetooth, HD Radio, and App connectivity. However, its functionality is entirely dependent on a proper electrical connection. The wiring harness is the bridge between your car and the stereo.
Note: While this guide uses the AVH-X3600BHS as the primary model, the wiring is identical for most Pioneer models of the same era (AVH-X models like 2500BT, 2600BT, 3500BHS, 3700BHS, etc.). Always verify your specific model's sticker.
