Can someone help me wire in my car radio - when all the colours don't match up!

[WriggleJiggle]

I don't suppose there is anyone who can solve this for me, but worth a try I guess.

My car radio has the standard radio harness.
My car has 14 randomly coloured wires (no harness).

Does anyone have an idea about what any of these wires are?

1. pink / black

2. pink / white

3. green / black

4. green / orange

5. blue / red

6. blue / orange

7. yellow / blue

8. yellow
   Nos 1-8 possibly the speaker wires?

9. red / black

10. orange

11. purple

12. pink

13. black / yellow

14. black / pink
    Nos 9-14 to connect to ignition / ground / dash light / power antenna / battery ?

One of the wires (black / yellow) is very big and fat
Whenever you touch another wire to the pink one the aerial jumps up and down, except for the orange wire which doesn't make it do anything.

Oh dear, this must be one my most bizare posts ever

I shall ask my dad for you in the morning, he works with cars

No

But make model of car

Make model of head unit.

Try an google the head unit+ wiring

or try yellow pages for in car entertainment. Local shop should do it in an hour.
