Notes:

- Not all wires are used in every installation.
- The

orange/white

wire may not be connected if your vehicle doesn’t support dimming.
- Always double-check with a multimeter or vehicle-specific wiring diagram to avoid damage.

Let me know the

model number

of your Pioneer unit or the

car make/model

, and I can give you a precise match or a vehicle-specific pinout.
