You've already got the hard part done! The contacts from the front-panel switch need to be connected in parallel with the footswitch jack lugs, so that the relay gets operated by the front-panel switch the same way as it gets operated by the footswitch. Depending on which lugs on the jack you connect the front switch to, you can either have it so the Overdrive can be operated by the front-panel switch, even when the footswitch is plugged in, or else so that the frant-panel switch gets disconnected when the footswitch is plugged in and all control is then from the fotswitch. If you look at the jack contacts fairly carefully, and see how the contacts are made and opened when you plug in a jack, you can pretty easily figure out which pair to use.
