Fan shutoff unit is not working properly but I cant figure out how to
remove the wires from the control unit(honeywell) Have to get it out
to determine if there is another in town as the piece that goes into
the furnace can be different lengths... -30 tonight and don't want to
just cut the wires as there is not enough left to strip them again and
re-install..... any ideas anyone...

Look closely, should be a small slot next to where the wire goes in
where you can insert a tiny tool (jeweler's screwdriver?) to release
the wire.

If you get a new control, pay attention to the jumper that may be
factory installed; you may or may not need it and if you get it wrong
the controls can be damaged. Read the directions...
