I have a Speedway Motors aftermarket harness which provides one 12v ignition wire to power any and all electrical gauges. I currently have it providing power to my tach, but would also like to use that same wire to power my volt meter, and probably later to the fuel gauge. My electrical skills border on beginner/intermediate, so I was curious as to how you all would tackle this, before I just reach for the can of wire nuts and "rig" it.

Thanks in advance!
