Re: 1948 heater wiring

Power for the heater should be provided by a single loose wire running between ign sw GA terminal and the BAT terminal on the heater switch. There will be an inline fuse holder somewhere in that length. The owners manual says the 30 amp heater fuse is positioned under the clock so I would expect the wire to be laying toward the bottom of the dash. You might be able to find the fuse holder and then identify the wire.
