Which Ceramic heater rods?
The 900 series ceramic soldering iron elements are probably what you want
For one of those you'll need a power supply up to 24V and 5A and a step down controller for VV control OR you can cut the handle off and use the soldering iron controller for temp control.
Either way the.wiring is pretty simple.
There are 4 wires on the A132x elements - 2 for the element and 2 for the sensor.
If you're cutting the handle off - unscrew it and make a note of the connections > cut the board off > slide off the handle > reconnect the wires as per your notes.
If you're going VV - the red wires are usually for the element (and the blue wires are usually for the sensor)
I've made a few of these style vapes
Easiest build I've done was using a 7th Floor Vapes LSV heater cover + a cork + a cup and a 936D soldering iron so I recommend having a look through their spares for parts for your first build.
