First, using an email address as a username is asking for it. Every 'bot and spammer will now have what they are sure is a legitimate email address; get ready to be blasted as this is a public forum and google bots as well as every other 'bot has access. (If our signup page does not say that, it damn well should.)

Second, the manual has so many errors, it's not worth even trying, IMO. If you want to try, here you go.
I tried to make sense out of what I found on page 8W-47-6 of the service manual, its obvious the diagram is wrong.

BL/RD Coil 2+
BK/YL Coil 1-
VT Coil 1+
RD/ Y Coil 2-

PK Coil 1-
DG Coil 2+ If this speaker acts odd, reverse these two wires at the speaker.
BL Coil 1+
BR/RD Coil 2-

Personally, I can tell you that you are probably wasting your time. The factory's "4 into 2" and dual coil speaker configuration was asinine in the 1990s when it was introduced, to say nothing of 2004. Its now 2023, the reasonable thing to do is to throw away those idiotic dual coil speakers and put in single coil speakers and a modern amp, wiring for four channels at the same time.

But, go ahead, knock yourself out on that over designed, under performing abortion of a sound system.
