Hold the wire clippers, I think we have a problem.
Stan and Rod,
Last night when you guys kept posting and I kept watching, I think I found an overlooked issue. Please follow along.
Below is a copy of the diagram that Stan had originally posted and I had marked my modification on, in purple. Not having a board in front of me to trace, I didn't realize that the toggle switch connections that were missing needed to be in the mix....until last night. I then added the switch connections as shown.

For the modification to work, three things are needed:
1) The connection between Relay Common and the appropriate ACC terminal cannot be broken.
2) The connection between the selector switch's center contacts and the board's electronics cannot be broken.
3) The connection between 1 & 2 above must be broken.
All three are true on the drawing above.
When looking at the picture below, discussed last night, I wondered why Stan thought it was harder to modify. The traces were different, but I saw BLK and RED wires in relatively the same position as before.

I referred back to this earlier picture below, showing the clip point, and then it hit me. If those wires are coming directly from the center of the toggle switch, they cannot be cut. Somewhere the rectifier connects to that trace to feed the electronics, unless the switch's wires land somewhere else on the board and the wire marked "disconnect" is just a jumper.

I hope that I am wrong. Please check the feed wires from the toggle switch and locate the rectifier's AC connection point, on the available versions.
