The shifter operates a "momentary on-off-momentary on" switch inside the left side switch module, i.e., it something like this. When you push "+" it makes contact from common to side A and when you push "-" it makes contact from common to side B. This switch is part of the internal processor in the LH module and does not connect to any wiring whatever outside of the LH switch module. The switch module is a Can Bus processor that sends digital signals to the ECM and TCM that tell them to execute a shift. That's why you can't connect anything into the wiring harness and have it work.I knew you guys would come up with a number of ideas and I thank each of you. After I start my treatment I will find which direction to head in. I'll keep you informed as to what I end up doing. Thanks again!
A person MIGHT be able to get to the inside of the LH switch module and connect wires to the shift switch and add a "momentary on-off-momentary on" toggle switch in parallel to the handlebar switch. This new toggle switch could then be connected to a foot operator of some sort.
My first step would be to see if you can find a used LH switch module from a motorcycle salvage yard. Take it apart and see if it's feasible or even possible to connect wires to the shift switch. I'm inclined to think it could be done. A new one costs over $400.
Another possibility is find a solenoid that can be powered to move in both directions. Connect it to a foot operated switch like I suggest above. Connect the plunger to a cable, something like a bicycle brake cable, and run that up to and connect it to the shift paddle. This approach uses the solenoid to mechanically operate the shift paddle with electrical power. The first idea above is to clone the electrical operation of the shift paddle.
Hope this gives you some ideas to chew on.
