Everything works as it should apart from the speakers, both radios have the external amp which is connected, the only difference is the 708 only had outputs for front speakers, the 906 has front and rear but I only connected up the fronts. The problem is only the rear 2 speakers work. |
You've got a 940 haven't you? The diagram you use isn't applicable to the 940, some of the wire colour codes are different.

Both of those are for later cars than yours, i can't find one for a 1990 940 but would expect it to be similar to the 1990 740, not that i can find one of those for the audio system, just the basic ignition/injection diagrams.
