PA300 Wiring Issue

I have an older PA300 with a silver faceplate, but i cannot seem to find the right wiring diagram for. It does have a the newer style 12 pin Molex plug, but only 9 are used. Every diagram i have seen is showing a BLUE "Speaker Common' wire. Mine does not. What mine does have, is a YELLOW wire running to the bottom side of the power supply nest to where the ground goes in.

Here is a layout of the pin setting:

1 2 3

4 5 6

7 8 9

10 11 12


1: 22g White

2: blank

3: 22g Brown

4: 22g White/Yellow

5: blank

6: 18g Brown

7: 18g Black

8: 18g Green

9: 18g Red

10: 18g Black

11 & 12: blank

I know what the Red, Blk, and green are. I can also assume that the Wht and Wht/Yel wires have something to do with Horn ring, and Brn is probably skpr.

Any help is very much appriciated. Thanks!
Problem figured out. The Yellow wire and one of the Black ground wires go to the speaker. The 2 brown wires are for Radio rebroadcast. i guess that is what friends and 2 hours of beating your head against the wall will do!!!
