Default Problem hooking up innovate wideband and turbo timer

I have been struggling hooking up my innovate wideband for the past two days. I only plan to be using it for its Wideband function at the moment, and successfully wired it so that the 02 sensor heats and calibrates and the test light also is functional. Problem im having is that when i plug in the display to read the actual AFR it does not even power on and remains off. I have the 12V constant wired to a fused power lead in between the battery and my amp and i have tested it with a multimeter to ensure it has power yet the display still will not turn on. The power lead for the O2 sensor heater is connected to the cigarette lighter and functions just fine, im not sure what the problem is exactly. I have my grounds located under the steering wheel column and they seem to be more then adequate yet still no luck. i was hoping someone may have some insight into the matter. thanks!

As I am reading this you have the gauge connected to a different power supply then the actual Wideband sensor??
Maybe that is part of the problem, as the cigarette plug does not get power until the engine is running, so the gauge (which gets power earlier??) does not see a working sensor (as that gets power a fraction of a second later.
My old PLX and current Stack do not function correctly if one connects the lambda after the gauge is already on, they only work when powered on simultaniously.

As a test can you not run a ground and fused power directly from the battery, and connect the gauge and the sensor to this.This would take 10 minutes at most, just leave the door/hood open, to test if it works.

If not the gauge is probably DOA , if it works you know the problem (the 2 components getting power at sligtly different times)

I figured you may be on to something so i gave it a shot, No luck.. Im almost hoping the display itself is pooched just so i don't have to feel so self conscious about my wiring job
