Help Me Please

So I received my VEI Boost Gauge a couple days ago and it's been an ongoing project to install. I HAVE installed boost gauges before and I think it might just be a defect in the gauge itself. Anyone that has installed this in their B5 S4 please chime in..

So there are 3 wires, 1 Black, 1 Red, and 1 Green.

I grounded the black, ran the red underneath the dashboard and tapped into this:


Than I put the green on a light switch, so it can dim and brighten depending on time of day.

When its all said and done, the gauge lights up but an error comes up..What am I doing wrong?

Please chime in on EXACTLY where you tapped in your VEI boost gauges please!!

(I have searched for the past 3 days, so please dont tell me to search.)
