FiatPunto Car Radio Installation?

Hi everyone,

I'm installing my Pioneer CarRadio [DEH-1600UB] into my Fiat Punto Grande 2006, but encounter issues attaching the wires correctly.

The connection consists out of 2 block with 8 (2x4) outputs. I'm having issues with the block with 5 outputs of the car.

I can't attach a picture on here, so I will describe the position/colors of the wires below:

Position on the block is numbered:
1. / 2.
3. / 4.
5. / 6.
7. / 8.

The wires coming from the Fiat dashboard have the following position/color:
1. black/white
2. N/A
3. red/white
4. pink/white
5. grey
6. N/A
7. N/A
8. black

The wires from the facia have the following position/color:
1. N/A
2. N/A
3. N/A
4. yellow
5. blue/white
6. N/A
7. red
8. black

So, only position 8, the black cable is on the same position.

Anyone knows how to connect the rest of the wires correctly?
