This alternator-spec wiring harness is designed for the Austin Healey BN4 (1956–57). It replaces the original dynamo loom with upgraded charging cables to cope with the higher outputs of a modern alternator, offering improved safety and durability.
The harness covers the full BN4 electrical system, excluding the overdrive loom, headlamp pigtails and steering column harness, which can be ordered separately if required.
If fitting a Dynator or Dynalite unit, a different specification loom is required. These can be supplied to special order on request.
Available to special order; please enquire for details.
