Can't seem to find this schematic anywhere.any help appreciated... thanks,charlie

This diagram is for the wiring of the blower control and magic HVAC selection switch (HEAT-OFF-COOL) that is located on the furnace. See paged 8 and 9 for this wiring.

Note the other wiring for the furnace burner etc is all common style wiring that you should have no problem with.

Here is a parts list for that and a few other units.

The wiring diagram is actually on the back of the plate that holds on the hot surface igniter united 1018.
