  • Great Tutorial. I’ve been working on wiring an external SOS switch on my motorcycle dash and concealing the spot connect so that I can track the motorcycle in the event it’s ever stolen. I’m getting somewhere around 2.7 volts to the switch but can’t seem to activate the SOS when using my own switch that I’ve soldered on. I’m guessing the switch that I removed must be a multiplexer or something beyond my understanding. Any ideas on how to wire an external SOS switch?

No public wish lists :(
