GTE Digital dash (FS Spacecruiser)

Hi guys

I have just bought a digital dash from a astra gte 8v, putting this into a
cavalier 4x4 is this a job a novice could do?

also i have on ebay a spacecruiser for sale it's located at
http://tinyurl.com/dc7l7

regards

 

the job itself is not difficult although modifying the dash surround can
be(i've got the exact conversion into my cavvy 16v although as per yours the
wirins should pretty much be colour for colour. the only thing you will need
is the gearbox sender plug for the speedo i hope you got this with the dash
as they are extortionate to buy from Vauxhall,


the following is from Cavweb



Cavalier MK3 - Astra GTE digital dash wiring guide



First of all remember an astra digital dash does not have :-



1) 4x4 light

2) check control lights



A cavalier dash has 3 connectors:-




1. large connector, fully populated behind rev counter - does most things

2. large connector, few wires behind petrol gauges - does ABS & 4x4

3. small square one for check control only





An astra Digital dash has 2 connectors:-



large connector like cavalier one which does all lights at the bottom of the
dash small pins with lots of pins which does everything else

You will need to run 2 wires from the indicator switch to the dash:-

Indicator Right Black/Green 1 large

Indicator Left Black/White 16 large




For the illumination and dimmer to work correctly you will have to connect
the
White/Yellow wire (lights on green light) & Grey/Green from pin 16 (relay)
together and run to the fusebox grey/green wire fuse 9 bottom pin.


You will need to add the speedo sender to the gear box and connect:-

black to ignition

brown to ground

blue/red to 21 small pin and Blue/Red wire of the cavalier loom to drive the
4x4 and fuel computer



Speedo calibration



There is a switch on the LCD dash which changes the speedo calibration
depending

on what tyres you have and gearbox etc.



There are 2 options on the dash (for astra)



175/70*13 (185/65*14 Astra GTE 16v models)

185/60*14 Astra GTE 8v models



You will have to set this the best you can by trying position 1 and 2 and
comparing

the speed reading you get with the fuel computers instant speed reading
found

by putting the fuel computer into average speed mode and then resetting it.

Even if you get the fuel computer and speedo matching it may still not be
right,

to check follow a car at a constant speed.





To get the oil pressure gauge working you will need to replace your oil
pressure switch

with an oil pressure gauge sender and combined pressure switch.



from a cavalier 1984 GL,CD, Astra Mk1 SR/GTE (about o44 new)

or Astra Mk2 GTE, Calibra 1995 (about o66 new)



The expensive ones have a water proof connector like the cavalier one.

However the o44 is just as good !



If you have an expensive one simply plug in the water proof connector to the
cavalier loom blue/green

And run a new wire from the other terminal (push on) (blue/yellow) to 12
small.



If you have a cheep sender cut off the water proof plug on the cavalier loom
and add a spade. then connect to sender.

And run a new wire from the other terminal (push on) (blue/yellow) to 12
small.
