I already looked into switching the wires. I think there are only 4 wires from each handlebar. I believe all the wires are used to send different bits to the module and the module determines what function is activated. So it's not just as simple as switching wires.
I would think the modules are what transmit the messages based on what switches it sees being pulled... That is what the module is for. If the bits were coming from the handle bar why would you need a module?
I suspect that what is really going on is that each switch is set up as a MUX sense wire. So for the PTT for example, if you PUSH, Move UP, or DOWN, the switch is making contact with different resistor values. The Module is "Looking" at the resistance on this wire. And when it senses a movement, the module then transmits the message to the network.
If I find time I'll poke around a bit to validate this. But I really doubt there is anything smart in the switches if there are separate modules down by the forks.
EDIT: BTW Joe, not saying your wrong. I just want to validate it, that's all... From a design perspective it would be overkill.
