eg gauge help

[cprtyler]

hey guys i have 94 civic eg 4 door and it has a b18b swap in it. the swap is obd 2 along with the harness and ecu (p75). i was driving down the road and then all of a sudden the rpms and speed needles dropped the i noticed that gas gauge started falling and the water temp did the same, i thought ok the gauge cluster went bad the i started to turn and my blinker didn't work any ideas? is there a relay that this all directs to?

thanks for any help
