I am trying to install an alarm system,which includes (keyless/alarm/remote start), to the 2005 Mazda 6 Sedan. But I'm having a hard time looking for the Tachometer Wire for the 2005 Mazda 6 Sedan. Can someone give me a schematic for this vehicle or tell me where it is? But, really, it is hard to find the tachometer wire! Someone please help!
