Default 68 Wiring Question

I just replaced my tach and I have a wire that I cannot remember where it was connected. It is a larger gauge brown wire that comes out of the harness just before the ignition switch plug. I have the wiring diagram and it just shows the wire terminating at an unnamed rectangle on the diagram
Any guidance would be appreciated.

I think that wire goes to the radio capacitor.

Default Goes to radio capacitor...

The capacitor on mine was mounted to the back of the tach. Not sure where it's really supposed to be mounted, but I put it back in the same place.

We recently discussed this in the below thread:

There is also an ignition switch accessory tap that is brown. Test for power with ign switch off then turned backwards counterclockwise to see if it has power then.

Those are the only 2 single brown wires on my diagram.
