There should be two caps switched into where the original was removed. One lead from where the original cap was removed should go to the center of the switch. Each end of the switch should have each of the two caps soldered to it. The other end of those two replacement caps should be soldered together, and that connection should be wired back to the other end of where the original cap was removed.  :icon_eek:

I believe this shows the caps in series when switched in, I don't think that's what you want. It's wired one cap or the other, from what I assumed.

Switched one way, one cap is in the signal path going back to the board. Switched the other way, the signal path goes through other cap goes back to the same connection.

You only need half of the switch you are using, it's a very easy mod, you're just switching in one cap or the other.
