Where does the black fuel sending wire go

So was the car running before this? Is it a rally dash? On my cuda I believe main feed comes in the round plug. Heres a pic of mine, 8 male pins.

Where does the black fuel sending wire go. What stud? I wrote in sharpie on theback of the dash . When it was in the dash. I'm checking to see if I'm correct. Also I'm putting on an IVR3 limiter. I'll pull away the contacts inside my fuel gauge. BTW 69 Barracuda. Whenputtingin an IVR3 limiter. What happens to the condenser/capacitor on the back of the Instrument panel??? Also on the power circuit board I have a red wire and a red/blaDSCN9769.JPG ck stripe wire that share the same stud. Which stud do these tow wires attach to. THX.
