The only plane I know of that had interconnect is the Ercoupe.

Our '51 TriPacer (S/N 13) had rudder-to-airleron interconnects which we
hooked up before annual insp but tied off before anyone wanted to fly
it afterwards. I never understood why there was an interconnect.

When the Pie Chaser was certified (about 1951), interconnect was all the
rage among manufacturers, including Beech and Piper. Personally, I have
always found interconnect to give an objectionable feel to a plane. I
hate the extra load on the controls!
