Hi,

I bought a used D3 off of ebay and some of the wires are missing. Called Pioneer Tech Support. Got what I was looking for from them, and thought I would post it here incase anyone else ever needs it.

Pioneer does their pin-outs from top left to bottom left working towards the right. As a result, all Odd Number Pins are on the top, and even number pins are on the bottom. I will stick with their System. Pins are as follows:

1. Gray (RF+ Speaker)

2. Purple (RR+ Speaker)

3. Gray w/Blk (RF- Speaker)

4. Purple w/Blk (RR-Speaker)

5. White (LF+ Speaker

6. Green (LR+ Speaker)

7. White w/Blk (LF- Speaker)

8. Green w/Blk (LR- Speaker)

9. Lime Green (Parking Brake)

10 Pink (Speed Sensor)

11. Violet w/Wht (Reverse Positive Input)

12. Orange w/Wht (Illumination)

13. Auto Antenna Output

14. Red (Accessory)

15. Black (Ground)

16. Yellow (Battery Positive)
