I've been trying to install these damn Prosport gauges for the better part of 2 weeks!

I've had it hooked up to a switched 12V source and the gauge would light up when the key was turned but it would not do the opening ceremony or display any values.

I've had it hooked up to a constant 12V source and the gauge was always lit up (even w/ the key turned to off) and it still didn't perform the ceremony or display any values.

I have an Autometer A/F gauge installed as well (also not working)
Power wire hooked to cigarette lighter
Ground wire hooked to CPU ground (via turbo timer wire)
O2 sensor wire hooked to CPU O2 sensor wire (via turbo timer 02 wire)

I know it takes a while to warm up the 02 sensor, but I let the car idle for 10 mins and neither the gauge or the TT showed an A/F value. The gauge never lit up and the TT displayed dashes (the TT functions fine and was displaying approximate A/F values until the gauge was installed.

If anyone knows how to wire gauges and could tell me what's wrong (be it wiring or the gauges themselves) I'll buy you lunch if you take a look at this stuff and help me fix it.

I HATE ELECTRONICS!
