Verba Phonic switch wiring

Need a wiring diagram for the "reverb" switch on a 1968 GTO.

There are six wires connecting to the switch. It looks like 3 in and 3 out.

Right now, the front speaker works with Reverb OFF. With the switch in REVERB, both speakers work, and the reverb works. In the REAR switch position, only the rear speaker works. My understanding is the front speaker should work in any switch position.

Could be a problem in the switch, as the amplifier and reverb cut in an out as I move the switch or the wires.

Answering my own question

I did find a wiring diagram for that radio, and will provide it to anyone who needs it.

The reverb switch has three positions, and it turns out OFF means front speaker only, REVERB means front and rear with reverb active, and REAR means rear only.

I also made a drawing of the switch with the positions of the six wires that connect to it, and will keep that in case anyone else runs into this issue.
