The tach cable for the early BN4s (through #38837) is the same length as the BN1s & BN2s (2' 9" according to the Moss catalog). I'm assuming the routing must be different for these early BN4s than that of the later six cylinder cars, since the later cars have a cable length of 4' 0".
Does anyone know the routing for the pre-38837 Longbridge BN4s? There appears to be two same sized holes on either side of the voltage regulator. Every six cylinder Healey I've ever seen has the tach cable going through the left hand hole (if standing in front of the car), but there's no way mine will reach if I use this same path. Should mine go through the right hand hole, or is there another route that I'm not aware of?
