1983 VW Polo Mk2 stereo wiring diagram

I have a 1983 Volkswagen Polo Mark 2, i need a wiring diagram showing me which wires are ground/constant/illum e.t.c

If this helps i have a picture of the only 4 wires for the stereo: (the one which looks orange is actually brown).

with that car all you need is a simple test light that will determine which wire has power all the time., ground could just be a good piece of metal. you dont really need illumination. the two main wires are constant 12 volts which means the test light lit up at all times. and switched 12 volts. which means test light turns on and off when you turn the key on and off. a test light you need is less than 5 bucks and can be gotten anywhere autoparts are sold or your local wallmart. hope this helps.

mecp certification is not always needed. I have it and it has not helped me out at all. my experience out shines it.
