Tachometer Voltage at Pin #3 on Speedometer - 2011 RKC
Installing tach on 2011 RKC. Have read several threads and depending on the year, connection options change. The popular "pink" wire, pin 3 on ecm, does no exist on my bike. In fact, pin 3 on the ecm connector is plugged. That leaves me with pin 3 on the back of the speedometer or tapping into coils. I prefer to use pin 3, keeping everything under the dash and this tach signal should be cleaner. Apparently the speedo takes the serial data signal in at pin 2, then outputs a clean tach signal in pin 3. I bought the terminal pin and wired the tach up to pin 3 but tach still not responding. Can some one tell me what the voltage out is on pin 3 on the back of speedometer? I want to verify the signal before returning the tach.
Thanks!
Thanks!
