Sounds like the short bit of speedo cable (between the transfer box and the
speed transducer) has snapped.part # PRC 6320
if it's making the engine run rough on idle then that's what i'd look for
first.
easy to get to, crawl underneath with a 10mm spanner, behind the handbrake
drum you'll see the cable go into the transfer box. release the bracket and
the cable will pull out. unscrew the other end from the speed transducer.
you can then spin the cable inside the cover and see if it's broken.

I just installed 4.01 gears and my speedo was reading 70 when I was
going 45, so I broke down and bought the VDO programmable speedo that
many on the list have. Bruce Bonar provided the list (via the FAQ
section) with the right part numbers (for a '94 or '95) - the speedo is
437155, the sender (Hall-effect speedometer cable) is 340011. And Bruce
explained that you've got to go to a speedometer shop and have them make
a new end for your old speedo cable to use it as an adapter. When I
called a local speedo shop they didn't have a clue, so I called tech
support at VDO, and here's what you tell the speedo shop:
1. Tell them you will bring in the new VDO sender/cable and your old
cable.
2. Ask them to install a 7/8" x 18 male end onto your old cable. This
new male end gets installed on the speedometer end of the cable, and
this (newly shortened) cable only needs to be 3-4" long. The existing
female end of your original cable is retained.
3. Using this new short cable as an adapter, screw the original female
end into the little frame mounted box right where it used to go, and
screw the new male end into the female end of the VDO sender/cable, and
zip-tie the sender box (which is a cube about 1-1/2" on each side) to
the frame so it doesn't bounce around.
4. Hook up the speedo end of the sender/cable to the VDO speedo.
5. Calibrate per directions.
6. Drive around in complete confidence that your speedometer is accurate
for a change.

When I put on the 33" Swampers w/ 4.10 gearing my calibrated VDO Speedometer told me
I was going about 69 mph when the speed limiter shut me down. Very frustrating as
you head up I-5 where the speed limit is 75.
The speed limiter get an output "upstream" of where the new speedometer cable
connects. The gearing and tires are what did me in.

If the transducer/sender unit that fits near the gearbox has the same speedo cable fitting as the standard LR part, then you can use the short (About 7") cable off of the Range Rover 4 speed autobox. That's what I use on my V8i 90 to run the speed transducer. Part number is..

On my '94 I used:

Total cost $175.
You'll also need your local speedo shop to make up a very short adapter
to connect the sender where the cable was previously connected. This is
because the threads are not the same. My cost was about $20 while I
waited.
Wire in the new speedo using directions supplied by VDO.
Run wire from sender to speedo using same routing as removed cable.
If you need better directions than what comes with the VDO speedometer
than you shouldn't try it.

The original OEM tachs on 94 NAS D90's are VDO's, as are the other gauges I
believe. The problem with the stock tach is that an alternator change
eliminates any semblance of accuracy. My replacement VDO can be calibrated.
The "Vision" series of gauges are also MUCH easier to see, the lighting has
been greatly improved.

As far as I've been able to determine, the D90 should be the same as the

An easy way to mount additional gauges in a D-90 is to use a center dash
panel out of a 97 soft top. It goes in the center of the dash in the parcel
tray area directly above the hazard switch/clock. You can easily fit 3 21/16
VDO or similar gauges neatly. This will not work on a station wagon as the
rear wiper switches are mounted there. I did this in my 94 and it turned out
great. For a water temp gauge with numbers, the sender must be changed. I
found that running a 3/8 pipe tap (I think) into the original sensor mount
hole in the manifold allowed fitting the sensor. On the oil pressure sensor,
I drilled out the center of one of the factory block off plugs on the pump
and tapped it to 1/8 pipe threads. By using some 1/8 pipe elbows and tubing,
I was able to mount the sensor. The oil pump uses some really large, odd
size plugs and I could not find a sensor to screw directly in. NAPA sells
VDO gauges and sensors and all parts are available individually. I will be
installing a similar setup in another D90 in a couple of weeks--I'll try to
come up with part numbers if possible.

The trans temp sender is in the cooler line that runs by the power steering
box. It is right by the box. It is tied in with the t-box sender and either
will turn the gearbox overheat light on. It is enclosed in a rubber boot
that fills up with water/crud which will sometimes corrode the sensor and
turn the light on even though there is no problem. Sort of like mounting it
in a bucket. I am not sure if there is one on an auto trans D-90 though, I
never had a problem or thought to look.

yeah. on my 94 D90 the idiot light sender is on the oil pump housing above
the filter. LR was nice enough to provide a second plug higher up for
isntalling a second sender for a guage. I went electrical so I had the plug
tapped for the sender, he would tap it for the bushing. which is probably
the same 1/4 NPT. You cannot get an adapter as the hole is 1/2 x20 thread.
If he goes electric this would be the way to go. unless he wants to spend
120.00 on a LR electrical sender, and some rediculous money for the guage. I
used VDO guages.
Alan Dobbs[SMTP:gulfcmt@flash.net] added:
I mounted a mechanical VDO and ran wire braid ultra high-pressure hose.
So far so good, and no problems with over 3 years of abuse.
If it was to break I believe it would be caused by chaffing (rubbing against
something) and not a over pressure blow out.

Subject: RE: [D90] Amp or Volt gauge?
I've been thinking about the same question lately, Cliff. They had a big
go-'round on the LRO list about this a couple months back. Personally, I
think I lean toward a volt meter. Mainly for the easier installation. I
too am a little uncomfortable running all the juice for the truck through
that ammeter. I've done it before. It's not hard to do well. The volt
meter is just simpler. But, it's a lot of personal preference, either will
do okay for the normal car circuits. One advantage of a volt meter is you
can see how far it's dropping when you're cranking the engine or winching.
An ammeter can't give you an idea of battery health under those conditions.
One thing I would recommend is to get a gage that has a built in warning
light. Great as gages are for telling what's really going on, they aren't
great eye catchers since the difference between good and bad can be only a
few degrees of angle on a needle. This is especially true of electrical
gages which, by design, have to cram their full scale into 90 degrees of
travel. A warning light is a great attention grabber that will stick out to
alert you the instant an unfavorable condition exists. I think Clarke
Williams knows of a source for gages with integral warning lights.
------ Editor's addition --------
The source is Datcon Instruments
Especially the Illuma-Seal Smart Instrumants Series 2000, and 2001
Here's an example of a Series 2000 Volt Meter
------ end editor's addition --------
If the gages are anywhere other than immediately in front of the driver
(say, top of the d90 instrument pod) I'd be tempted to wire all of the
warning lights through some diodes and a relay, to activate a big "CHECK
GAGES" light mounted prominently in front of the driver. There's nothing
like having a rod knock cause you to look at an oil pressure gage reading
zero........don't ask.....
Until you get a warning light, one thing that can help is to orient the gage
such that the needle is pointing straight up under normal conditions. This
is why you see gages mounted at crazy angles in race cars. All needles
straight up = situation normal. Anything other than straight up will catch
your eye with a quick glance. When you're concentrating on the driving,
you'll be lucky if you can spare even a glance.
Best of luck,
-Dave G.

If you want to easily fit a voltmeter and you don't smoke (how can these two
be related you ask?)
Where the cigar lighter is on the Defender dash, there are two 52mm holes
behind the plastic panel that holds said cigar lighter and the rear
wash/wipe switch on SW models.
If you can live without the cigar lighter (I can, I don't smoke or run any
'plug in' accessories) then remove the lighter and you have an instant,
pre-wired, source of earth, ignition fed +12v, and panel light feed!
Just connect these to the back of the voltmeter and hey-presto!
I did it on mine, and verified it straight onto the battery with a digital
voltmeter and the feed through the cigar lighter gives an accurate reading.
