I have an ST205 cluster connected to my AT200 harness. After careful inspection, everything's connected correctly and SHOULD work properly. I'm having problems some problems. The needles on the temp and fuel gauge wont move(Temp stays on "H" and fuel stays on "E".) And the cluster won't light up when I turn on the night lights(3 green bulbs). I'm going crazy but the next step is to check the voltages, ohms, grounds, etc to see if there's power going through all that crap. Would anyone happen to know how much voltage should be passing through each wire and what to do if a certain wire isn't showing the correct reading? How do you check for a good ground? I would really appreciate some help on this so I can be up and running because it's scary not knowing how much gas you have or if your car's about to blow up. Thanks in advance, guys.

that temp/fuel part of the cluster probably wont work for you because of the factory boost gauge that also sits in that section.
