RZ, If you look at the back of the gauge it should tell what the ohms for the sending unit are. There are 2 GM styles, 0 to 90 ohms, and 33 to 230 ohms. Check with EM and see which sender they use. You may also need to provide a separate ground to the sending unit from the frame. Most of the time it is a mismatched sending unit.
Wire # 130 is gauge power on the dash harness. You can splice into that wire for the amp gauge.
