My despatch date is 18 April 1950. The car was sold by Hoffman in New York.
I could explain the turn signal wiring better. The car has what I take to be
the normal cloth wrapped harness, including wiring for trafficators that in
the saloon run over the headliner struts, and which in my car are wrapped
back and tucked in the roof rather than dangling down to there they would be
plugged into trafficators if I had them. The wiring to the front and rear
sidelights and brake lights are wrapped in with the cloth wrapped harness,
but the turn signal wires in front and back are separate single wires, not
wrapped with the others. So they took a harness for a trafficator car and
just added some extra loose wires for turn signals.
I don’t understand why there would be a RHD wiring diagram for USA turn
signal cars at all. I never see RHD Mark Vs here, I didn’t think they were
ever sold here, and I always thought having LHD was a major selling point
Lyons wanted for breaking into this market. I studied it for awhile before I
figured out that the only difference from the LHD USA diagram is the
location of the large terminal block on the inner valence of the front wing,
which will be on whichever side the steering column is.
The only difference between my saloon and your DHC should be that I have two
interior lights in the rear corners where you have one in the center of the
hood. I think you can use W76522 and just ignore the second light. My main
harness runs through the right hand sill and the interior light wiring
branches off at the right rear corner above the inner fender so that should
be pretty much the same as yours.
I agree that the Mark V turn signal system is much better than the double
relay brake light interrupter they used on all the other models through the

My MKV DHC ch. 647194 date of manufacture July 14th 1950 has
original flashers, no trafficators and the wiring is as per
the factory Service manual, except that for some strange
reason for the DHC the wiring is exactly like in the ‘‘RHD
for USA’’ schematic, which I think has got to be a typo
because AFAIK they only made these for the North American
market, in Europe and commonwealth countries they used
trafficators for a lot longer, also with MKVII’s.
Lucas Wiring Diagram No. W76422, which is for the Saloon (1949)
and the same for No. W76522 which says (LHD for USA) 1949
also Saloon, I guess they didn’t bother to do a new
schematic at all for the DHC, but it seems it is the same
except for the small differences of the interior light (No.
W76520 Coupe Mark V 1949 (LHD Export Models)) and the fact
that the routing of soem cables was a bit different due to
the different body and sills.
My hacked and in poor shape wiring harness does carry the
wires for the flasher, I will be replacing the complete
harness when the body comes of for repairs and a bare metal
respray, but I think that won’t be within a couple of years.
I think it was a pretty neat solution with a separate relay
and double filament bulbs in the front side lights and
double bulbs in the rear lights, in comparison to some of
the MKVII relay and combined stop light and flasher hassle.

The original message included these comments:
My USA version Mark V has extra wire extensions for the flashing turn
signals, not part of the main wiring harness. Most Mark Vs had
but this is the way the factory did it for cars with turn signals.
