[Healeys] Overdrive relay.

If you use thinner wire to the overdrive relay it will add resistance to
the heavy coil and reduce its 'pull' and this might cause a slow overdrive
engagement. In the limit, it might not even pull the armature high
enough to disconnect the heavy coil which might then overheat including the
thinner wire you are suggesting. This might then be a fire hazard.

All of this might be the worst case and perhaps I am being alarmist but why
modify something that worked? They knew what they were doing when they
originally designed the car electrics.
