Does anyone know the best place to take power for a wideband o2 sensor kit?

 

I see they take a few amps due to heating the sensor iteself. I imagine I want it taken from the ignition wire at a suitable point that can carry the current. Going to take the dash panel off now and have a look. Not been behind there before but I assume ignition wire is easy to find. Anyone got any suggestions for location or best fool proof point to make the connection? cheers.
