The above mentioned smoke unit has 3 input wiress. My understanding is the outside 2 wires are for the hot and the middle wire is the ground. Does it make a difference which hot wire is connected to the feature output of an ERR Cruise Commander?  I am using a ERR "Puff and Chuff" module I've had for several years to sync the smoke and chuff.

On the 3 pin feed connector to the 8057-200, the outside 2 pins should be jumpered together at the connector. One side is hot to the heater and the other side is feed for the fan motor 5 volt dc circuit. The middle pin is chassis ground. So just one hot wire to the ERR P & C. You can BTW jumper the 2 outside pins on the solder side (top) of the SMU circuit board if that's easier.

Thanks Rod, I now remember a picture in an earlier post that showed the two outside wires joined into one but I had forgotten that. I will join the wires. Not getting any heat now but hopefully that will take care of the problem.
