There are quite a few types of variable resistors available. These are the ones that I am used to:

You turn the knob on top with a test pen to adjust the resistance. The numbers denote its size. In this case, "104" means that it is a 100K ohms variable resistor whose maximum resistance goes up to 100K ohms. "104" means "10" with 4 zeros behind = 100, 000. "103" would of course denote a 10K ohm resistor.

Now, there are 3 legs from the variable resistor. 2 on each side and 1 in the middle.

You will need to connect one of your wires to either one of the 2 legs on the sides, and the other wire to the middle leg.

You can solder the wire on.

And use hot glue to strengthen bond. Turn your variable resistor all the way to one direction and check with your multimeter the resistance between the 2 legs the wires are connected to.

On typical voltage mods, more resistance = lesser voltage and less resistance = more voltage. Thus in these cases, set the resistor to maximum resistance first before connecting to the hardware. This will ensure you start off with a low voltage.

Also, try not to adjust the voltage real time, as in adjusting the variable resistor while the PC is running. You can do that but it is more risky as sudden voltage spikes up or down and kill hardware.

As one end will be connected to the hardware, the other end needs to be grounded most of the time. It is easy to use a small alligator clip to clip the wire tip to one of the motherboard mount holes that are grounded spots.

Above shows the easy to use Ground spots, be it on the motherboard screw hole, or the graphics card, the whole length of the Slot bracket is grounded.
