In case anyone in the future is interested, I was successful in making my own foot pedal. I bought an inexpensive pedal that is known as a momentary pedal as it essentially just connects two wires shorting a circut to trigger the timer. I the cord has three wires but only two are needed. I connected the white and red with another longer cord and that cord I soldered to a DIN 3pin Male connector. I opened the timer just to make sure I was soldering the correct wires with the correct pins and success.
