Which smoke unit might matter, but one end of the smoke element probably has continuity to one pin and chassis ground via the screws that attach the PCB to the smoke bowl. That should go to chassis ground. The other element end should have continuity to a different pin. That would be center rail. You can use a loco switch to turn off and on the center rail power to the smoke unit. Not all have chuff control. Some pictures would help. G
