Ive Got An EA WAGon trying to install a taco it has 4 wires green black yellow white. ive pulled the dash out and had a look at the wires there. there is 4 wires by it self same colours. just wondering if they are it, it seams to easy ????

Upgrading From a Low Series Cluster to a Mid Series (Sports) Cluster
As mentioned above, fitting the Mid/Sports Cluster to a GLi/Futura Model Falcon is rather painless.
Some points though you will need to consider when sourcing/buying a mid series Cluster will include,

If you have smartlock fitted, make sure you get a sports cluster from a Smartlock Fitted Vehicle (EBII Onwards). Otherwise the Smartlock Jewel may not be present on the Instrument Cluster.

The Cruise control Lamp was only made available on EBII Mid (Sports) clusters, so If fitting / or if Cruise Control is fitted, you will need to get a cluster with the Cruise Control Warning Lamp Fitted.

If you have a 4 speed electronic Auto, you will need to make sure that you get a Mid (Sports) Cluster from an EAIII or onwards, as earlier clusters may not have the "Power" Warning Lamp.
If the above has not scared you off, then you are ready to start wiring some extra features to make the Cluster function correctly.
The Features you will need to wire up include,

The Tacho Input for the Instrument Cluster (So as the Tacho Functions)
Low Washer Level Warning Lamp (Which will require a Low Washer Switch, and wiring to function).

(taken from tech documents)

are you upgrading the whole cluster to a higher factory one as alfy said? or fitting an aftermarket fullysik big taco?
if its aftermarket it should come with instructions.

ohhh tacho! i thought he wanted to cook his taco!

I thought it was a taco themed interior, like a yellow wagon with lettuce, tomato and mince beef interior or something.

mmmmmmm actually, EA's look a bit like the Taco Bell dog

HAHAHA nah its a fully sick big after market tacho. i got it off my mate so i dont have instructions!!! and its a big green wagon with meat balls inside

Mason,
If you know the brand, see if you can find the makers website [Google] they may have a wiring diagram there. I doubt you'll find a Ford plug that will be meant for it.
If you can't work out who made it, go to the, for example, VDO, Smiths or Autometer sites to see if they have diagrams to suit. Two of your wires are for backlighting, probably the black is earth, try earthing that to a battery [neg] pole and touching each of the other wires in turn to the pos pole, start with the green. When it lights up, you'll know you have the lighting sorted. The other two wires often go to either side of the coil, that you'll have to check for yourself, [or hope someone who's done posts after me] as in is that where they go on EA? There could be two pins near or in the diagnostic plug to connect to, they're in an EA-ED w'shop manual.
If it is an adjustable tacho. check that it's set for '6 cyl'.
Nice looking car you have there, I went for the $20 sports cluster myself but I like easy. LOL
Cheers,
