If the connector is just the 1/8 or 3/16 ring connector just put it under one of the screws of the air horn or front fuel bowl screws.

If you want to mount it to the carb stud. Go ahead and mount carb as you should. Then pinch the ring connector between 2 clean zinc plated or chrome washers and torque down the nut.

The ground wire is typically connected to the carburetor itself by holley using one of the mounting screws that holds the electric choke unit.

The power side has to be a switched +12v source, most people use the power side from the windsheild wiper motor or they run a deticated wire to the fuse panel inside the car.

Example(not mine)

Why holley went that direction with adding longer wire is beyond me, it was fine just the way they had it as you can see from the picture i posted.

BTW.... which carburator did you get, the 670 or the 770 ?

Ground on this one will work just fine.

If your's has the larger ring crimped on and will fit on the mounting stud, just ground to the stud.

Once mounted you can test by running a 12+VDC jumper wire to the hot side of the electric choke. Choke should operate.

If not then check ground ... Check positive side of the circuit, check heating element of the electric choke. Etc...

I run a fused lead from the post of the alternator to 1 post of a 2 terminal oil pressure switch. The other side runs to the power side of the choke coil. The ground on mine goes to a temperature sensor that is bolted to the intake. This prevents the choke from trying to engage with a warm engine. Works great and no need for finding a switched wire since the power will only be present when the engine is running .
