[Healeys] Re - Fuse block terminal A3

John,

May not be relevant, but the earlier 100 BN2 diagram has the three
wires you 
mention plus the fourth is the supply to the fuel pump. Don't know
if this 
helps.....

My wiring
diagram shows three white wires attached to fuse block 
terminal A3. My wiring
harness has four white wires.

One goes to the overdrive relay, one goes to
the S.W. connector on 
the ignition coil and one goes to the overdrive switch.
The forth wire is in the wiring harness and follows the same route as 
the
wire that goes to the overdrive switch.

My original harness only had three
white wires.

What is the purpose of the forth wire?

Thank you,
John Spaur
