[Healeys] Healey Heater System

[Per Schoerner]

Hi
If you have a BN4, at least the one I worked with some time ago, then it 
doesn't have those oval holes. Instead they have metal tubes that are 
connected to the vent holes in the dash, the vent tubes attach directly 
to those tubes, e.g. no rubber elbows there. Be careful, those metal 
tubes are located very near the ignition key switch, a fact that had 
caused the wire harness meltdown on the car I worked with. Ended up 
replacing the harness, which was brand new BTW. I isolated the vent 
tube, (or the ignition key switch) with a piece of rubber hose before I 
reattached the battery.
