Threeway AUX Switch Help

[tenwatt]

I built this as an AUX switch for my Eventide Space and now I'm thinking it would be cool to add another jack to use one switch as a tap tempo for BOTH my Space and Timefactor.  Any ideas on how I would do that?

I thought that it would be as simple as running a wire from the tip, ring, or sleeve (which ever one I'm using for tap) of the existing jack to a new jack but that didn't work.
