What gauges are coming up off of their posts? Does it seem like they are at their initial reading point? So really we are concerned with wideband screen not coming on? I'd like to see that diagram and hear what you connected things to. Was the screen flashing or solid on?
It seems like the needle gauges are working correctly and illuminating when the lights are turned on, assuming you tested by turning on the headlight switch. Now just need to verify what wideband is doing and what wiring you did.
