Hi askwho69. Welcome to the forum.
Let me try to answer your question.
I can see in the MG squematics posted here, that V+ comes from CN3 at 13,14 and 15 pins. In the same way, V- comes from 10,11 and 12 pins.
If you check the TDA7293 Datasheet , in the first page, you´ll see that the chip receive V+ at 7 and 13 pins and V- at 8 and 15 pins.
So, if you connect CN3 with CN1 as you says (1-1, 2-2, ...., 15-15) you´ll routing V+ and V- to the right pins of the chip.
Hope help.
Regards.
