you can try to retrace the wires. The two 8 pin connectors on the schematics are Radio/HVAC display X1 and X2. X1 is the black one. The 44 pin connector is Radio X1 and the 20 pin radio connector is Radio X4. Retrace them so that they go to their correct location:
Display X1= pin 1 (Og) is power, pin 2 (BLK) is ground, pin 3 (OG) is a COAX but I don't see where it goes, pin 4 (WH) goes to Pin 43 Radio X1, pin 5 looks empty, pin 6 (bare) goes to pin 5 Radio X4, Pin 7 (TN) goes to pin 9 X4, pin 8 (YE) goes to pin 19 X4. The last three are wrapped in shielding.
Display X2= Pin 1 (OG) is power, pin 2 (BLK) is ground, pin 3 (WH) gets spliced together with pin 4 from Display X1, pin 4 (YE) goes to pin 4 of X4, pin 5 (YE) goes to pin 13 of X4, the rest look empty.
hope that helps.
