O2 Sensor Faulty?

[boomtheroom]

have just removed my autometer air fuel ratio gauge from my gtst and put it in my gtr but ist not reading anything ,was connected to the white wire on the gtst,and the gtr i connected to the same wire but it doesnt fluctuate like it should just sits there and doesnt move ,does the gtr use different o2 sensors than the gtst, if so where do i connect the signal wire from the gauge to, in the gtr?

firstly, the gauge doesn't give you an accurate reading, it will just look pretty. secondly, you probably have it hooked up to one of the heater wires.
