340 radio harness?

I'm sure this has been asked lots of time before, but I can't find it,
neither does a Google search produce any useful results, so...

What are the pin-out connections for the radio harness in my 340? IIRC there
are two pairs of black/grey wires, a couple of red/black, a green and a
brown.

Any answers or points to useful websites gratefully received!!

There's not that much to it. There are only stereo front speakers and
various power. (power in - sound out)

Black/grey - front speakers (check colours at door speakers)
Remaining wires test with a meter:
-Ignition on 12v
-Permanent 12v
-Ground

Thats all you need if you replacing with a standard unit.
