1989 760 Turbo Wagon -- Radio Wiring Diagram

[JohnR]

Good Day,
I am installing a new radio in my 1989 760 Turbo Wagon, but the wiring connector contains wires which are not on any of the 'standard' Volvo radio wiring diagrams. Cannot seem to find anything on the web, so I come here for your wisdom. The green, red/grey, red/white and tan/black are not on any of the standard wiring diagrams. Other wires appear to be okay.
VIN: YV1GX8756K0027856 -- I have included this if it can help my cause.
From the dealer, over the years, I have often heard him mention the term "new dash layout" -- that might be of assistance.
Many thanks for anything you can muster for me.
John

WHT = DL+
GRY/RED = DR+
RED/WHT = DL-

YEL = Speedometer
YEL/WHT = Dimmer and RHEO+
BRN/BLK = RHEO-
GRN/BRN = BATT+

DL and DR being left and right dash speakers.

1988-1990 Volvo 760 has the same dash layout as a 1992-1994 Volvo 960.
