FAQs
-
Will
this
fit
my
Z32?
:
This
harness
will
fit
any
and
all
LHD
Z32s
except
the
USDM
'96
(OBDII)
model.
Certain
models
will
have
some
leftover
connectors
as
these
are
designed
to
fit
such
a
wide
variety
of
models.
-
Which
do
I
pick
for
an
AT
to
MT
swap
car?
:
As
far
as
the
EFI
harness
is
concerned,
your
car
is
a
MT.
You
CAN
still
use
an
AT
harness
on
a
MT
car,
you'll
just
have
one
extra
connector.
Your
starter
inhibitor
and
reverse
lights
are
handled
by
the
Alternator/Transmission
harness,
which
is
a
separate
harness.
-
Which
CAS/injector
style
do
I
select?
:
While
we
can
determine
what
your
car
shipped
with
when
it
was
new
by
year/model,
these
cars
are
30
years
old
and
most
have
passed
through
several
owners
now.
If
you
don't
know,
you
just
have
to
go
pop
your
hood
and
look!
-
If
I'm
retrofitting
new
style
injectors,
will
I
still
need
an
adapter
kit?
:
Selecting
Late
Style
Injectors
here
will
give
you
the
right
connectors,
but
you
will
still
need
the
adapter
kit
for
the
injectors
themselves.
However,
if
you
select
Late
Style
injector
connectors
here,
you
can
omit
those
from
your
injector
adapter
kit.

Customer Questions
Question:
I have a 90 Na that was originally a automatic but now it is 5 speed swapped as well as having the new style injectors. i know the z1 harness states that it does not work with the auto models. which wiring harness do i need ? thank you
- Josh
Answer:
Hi Josh, you can use either one really. AT cars have an extra connector for the transmission control module. If you were to pick up an AT harness, it'll plug into that connector, but won't do anything of course. If you ordered a MT harness, it will just not have anything plugged into that connector (over by the relay box on the driver's side). No idea why Z1's harness won't work on a swap, but these work just fine.
Question:
So I want to 5spd swap my 93TT . I'm going to buy a new 98 Trans from you . But what drive shaft do I need,and if I buy a new wiring harness , do I purchase the 5speed harness and the 5speed alt harness?
- Justin
Answer:
Hi Justin, you would still by a MT driveshaft, MT harness, and for the alt harness, buy the Auto to Manual swap harness.
Question:
Hi I have a 1990 300zx twin turbo. With 740cc injectors and the 300 degree fuel rail. I’m looking to update my engine wiring harness. But I was not sure which one to go with? Early style or Late style?
- Irene
Answer:
Hey Irene, for that setup, you would want to select Late Style.

Very well made product. Packaged with goodies as well. Built and looks like oem. I will add I do wish some of the harness came out like the injector subharness. That part of the product was the best fabricated.
Ok so this wiring harness fit directly onto my '90z na with no issues. Here was my hang up - there were almost no identifying marks on any of the connectors other than the injector sub-harness. Don't freak out though because this website has a very detailed diagram of the harness including color coding which is handy for identifying the coils. I am very happy with this replacement harness and would recommend it to anyone seeking to evict their electrical gremlins.
Really good quality just sucks to install without pulling the engine but I got it done
