Hi

I have just purchased a non Triumph tacho to fit to the handlebars on my TBA. Can anybody help me with the colour coding of the wires in the tank binacle. My tacho wires are: Green to negative terminal of coil, Black to earth, Blue to lights, Red to ignition. My question is which wires do I splice into? Your help would be much appreciated. If this is the wrong forum - appologies

Regards
