Was trying to hook up my tacho and am having issues finding the wire from the coil to the diag connector to hook up a tacho (my EB does not have one) roughly where can i find this wire?

Im new to the forms but i m gessing its a ef i got mine hooked up to the computer connection in fuse box on right side of steering wheel there a connector in there with like 10 pins on it 1 of them is the tacko signal hope it helps

Try wiring into the negative side of the coil?

His car is an ED, fitted with a coil and an EF has coil packs. Little different with the wiring.

Also, why would you want to fit a Tacho to a car that already has one?

I'm gonna install one into my eb (doesn't have the tacho cluster) and have no idea how, are there any guide on how to do it?
Cheers

I use this to wire up a sports dash in my EB1 CFI sorry don't know how to add pic and was no able to find the link to this document hope this helps I used the Pink/Blue wire

Changing Instrument Clusters EA EB EDDocument Description

FIRSTLY: A Big thankyou goes out to Christopher Nee, for the pictures of the EBII Sports Cluster
This Document Describes the differences between various models of Instrument Clusters fitted to the EA-ED Series Falcons.
It also has information on upgrading an Instrument Cluster, modifications that need to be made, wiring information, and some points to watch out for when performing these upgrades.

With the EA series of Falcons (and Derivatives), there were three models of Instrument Clusters that were fitted to these vehicles. Theses Clusters Featured Orange Painted Needles, with an Indirect Orange (Natural) Illumination, an LCD Based Odometer for the High Series

Upgrading and swapping Instrument Clusters
With exception to the High Series (LCD) cluster, it is possible to change between different Cluster models rather painlessly.
All the Clusters use the Same Main Wiring Connector, but the High Series Cluster also have an extra connector for the Door Outline LCD Panel.
Also, the Main Cluster connector has different Wiring Connections going to it, when compared to the Low and Mid Series Clusters. Therefore when fitting a High Series Cluster to a Low/Mid Series Vehicle, you will need to re-wire this connector.

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).
• Replacing the Low Oil Pressure switch, with an Oil Pressure sender. (In order for the Oil Pressure Gauge to function correctly).
Information for these steps are detailed further on within the document.

Replacing a Low/Mid Series Cluster with the High Series Cluster Model
There are a few points that you will need to remember when considering to fit the High Series (LCD) Cluster to a GLi/Futura/S/Fairmont Model Falcon.
• If you have smartlock fitted, make sure you get a High Series cluster from a Smartlock Fitted Vehicle (EBII Onwards). Otherwise the Smartlock Jewel may not be present on the Instrument Cluster.
• 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.
• The Odometer Reading is stored electronically, via an EEPROM. This will either need to be changed to match the current Vehicle Odo Reading, or a cluster with a similar Odo Reading will need to be sourced.
• You will need to source the 20 Pin 3rd Electrical Connector, that is used to send the extra information to the Cluster.
If you have found a cluster, and a connector that matches the above criteria, then you are ready to start re-wiring the cluster connectors to make the new Cluster function correctly.
Re-Wiring the Cluster electrical connectors will be a long process, and just some of the electrical connections you will need to change will include
• The Tacho Input for the Instrument Cluster (So as the Tacho Functions - For Low Series Cluster Upgrades)
• Low Washer Level Warning Lamp (If not fitted previously - Which will require a Low Washer Switch, and wiring to function).
• The Oil Pressure Sender MAY need to be replaced to an Oil Pressure switch, if swapping from a Sports Series Cluster (The Low Oil Pressure Lamp may glow dimly when using an Oil Pressure Sender, instead of a switch)
• The Door Switch Wiring will need to be cut for EVERY Door, and a Relay, and resistor array will need to be spliced in, and wired up, for the Door Open LCD Warning to work.
• The Existing Wiring Connector for the Instrument Cluster will require HEAVY Modification, (I.E. Wires will need to be cut, and resoldered in to new positions), In order for the High Series Cluster to work.
Information for these steps are detailed further on within the document.
Swapping Odometer Readings
Obviously, when swapping Instrument clusters, you will want to keep the same Odometer Readings for your vehicle.
For the Low, and Mid Series Clusters, this is not too difficult, but will require the Instrument Cluster to be disassembled in order to do this.
Because the high series clusters have a digital Odometer, simply cracking open, and winding the Odometer backwards will not work.
So how is the Odometer reading changed ?
Firstly, you will need to know a little bit about electronics.
The Odometer Reading, as well as the Trip meter, Service spanner setting, and possibly other settings, are stored in a device known in the Electronics industry as an EEPROM, or E2PROM, (pronounced E squared Prom).
An E2PROM is an Electrically Erasable, Electrically Programable, Read Only Memory, very similar to the Flash upgradeable Computer Bios.
Anyway, without boring you on how an E2PROM works, the model used in the VDO Instrument Clusters is an X24C44 Surface Mount model.
It is this chip that stores the Odometer, as well as other readings.
When swapping Instrument Clusters, you will need to Re-Program this chip, if the Odo Reading is well outside of the desired range.
Unfortunately, I have no idea on how to re-program this chip, and as such, you will need to either take the cluster to an authorised Ford Dealer, or to a Instrument Cluster calibration specialist.
Adding an Oil Pressure Sensor
Because the Low and High series Instrument Clusters do not have an Oil Pressure Meter, these vehicles do not have an Oil Pressure sensor fitted.
Instead of the Oil Pressure sender, they use an Oil Pressure switch.
What is the difference between these Oil Switch sender thingies I hear you ask ?

The Oil Pressure switch is just that, it switches to Ground when the Oil Pressure drops below a certain level.
This means that the Oil Pressure switch is only good for Switching a low Oil Pressure Lamp On or Off.
If a Mid series Instrument cluster is used with an Oil Pressure switch, the Oil Pressure gauge will either show 0 Oil Pressure, or very very High Oil Pressure, with no intermediate pressure.

The Oil Pressure Sender has a constantly variable Voltage, that is directly related to the Oil Pressure.
Obviously, this variable voltage is required for an Oil Pressure gauge.
Likewise, if fitting a High Series Cluster, to a vehicle that originally had a Mid Series Cluster, then you will need to swap the Oil Pressure sender, with an Oil Pressure switch.
Without making this change, the High Series Clusters Oil Pressure Warning Lamp will glow Dimly under Normal Operating conditions.
With the Pressure sender, this is Normal, but obviously not ideal.
Finally the Mid Series Instrument Clusters also compare this voltage, and if the Voltage falls below a predetermined level, the low Oil Pressure Warning lamp is Illuminated.

The Oil Pressure Switch, and Oil Pressure sensor are located in exactly the same place, and as stated above, if fitting a Mid or High series Cluster, (I.E. upgrading from a Low series cluster), the Oil Pressure switch will need to be replaced with an Oil Pressure sensor.
These sensors are located roughly about 2 inches above the Oil Filter, on the Inline 6 motors.
The sensor also has a single wire coming from it, with a spade electrical connector.
The Oil Pressure sensor can be purchased from Wreckers for around $20.
Or alternatively, can be bought from Ford for around $50.00 - Ford Part Number EF-9D290-A
Wiring the Tacho for Mid and High Series Clusters
If fitting a Mid or High series Cluster to a Low Series Model, you will need to run 1 wire from the Engine Bay (More specific, the Pink Wire that is coming off the top of the Ignition Coil), to the Instrument Cluster.
For the Mid (Sports) Series Cluster, this wire needs to be run to the Lower Connector, Pin 8.
For High Series (LCD) Clusters, this wire needs to be run to the Upper Main Connector, Pin 2.
PLEASE NOTE : When Purchasing/sourcing an Instrument Cluster, ENSURE that you get the same model that is suitable for your engine type !
I.E. If you have a 6 cylinder, then you will need to source a 6 Cylinder Instrument Cluster.
Likewise, If fitting an Instrument Cluster for a V8, then the Instrument Cluster MUST BE OBTAINED FROM A V8 MODEL !
The Tacho sections for these models are different, and will therefore will be outside of calibration (I.E. V8 Cluster in a 6 will read a lower RPM, and a I6 Cluster fitted to a V8 will read a Higher RPM)
Adding the Power Line for the Volt Meter (When Fitting a Mid/Sports Cluster)
When fitting the Mid series Cluster, you will need to add 1 wire from the Battery (+) Positive Terminal, in order for the Battery Volt Meter to function correctly.
The Wire needs to be connected to the Pin 9, on the Upper Instrument Cluster Main Connector (The 12 Pin Connector).
If you are lazy, it is possible to simply run a wire from Pin 6 or Pin 7, on the Lower Instrument Cluster Connector (The Ignition Power Input Lines).
If you are up for the work, you could run this cable to either the ignition switch, or Radio Constant Power Supply. (Doing this will allow for slightly more accurate readings from the gauge)
Adding the Low Coolant sensor
This is a worthwhile modification that can be made to the EF and EL Series model Falcons, as it is relatively inexpensive to do, and it can be added to ALL Instrument clusters, (low, Mid, and High Series).
Considering the number of cases of Head Gasket Problems with the EF and EL, this modification could save you a lot of money !
The only models that do not have the low Coolant Sensor are unfortunately, the GLi models.
The Low Coolant Sensor is integrated in to the Plastic coolant Bottle, but can be added to an existing coolant bottle.
The part you will require is 10K888-AA, the low coolant level sensor.
This part simply screws in to the existing Coolant Overflow Bottle, but you will need to remove the blanking plug first.
Once this part has been fitted, you will then need to wire it up to the Instrument cluster
One wire is Black, and is connected directly to ground.
The other wire colour, Yellow/Red, should be connected directly to the Instrument Cluster, low coolant lamp, On the Right Hand Side connector, Pin Number 3.
Finally, you will need to add the Low coolant sensor Bulb to the Instrument Cluster.
This Bulb is located right next to the LCD Panel, on the Right Hand Side (With the Back of the Instrument Cluster facing towards you). The socket for this bulb may be blanked out by a round paper sticker, simply remove this sticker, and fit a new Bulb and Bulb Holder.
Adding the Low Windscreen Washer Sensor
The Low Windscreen Washer Fluid Sensor detects when the level of the Windscreen washer fluid falls to a level that allows only a few more seconds of Windscreen washer operation.
The Warning lamp is integrated within the LCD Odometer panel, on the EF and EL Series Falcons, and surprisingly enough, it is actually available on all clusters.
Unfortunately, if you have a GLi Model, without ABS, then you will not have the electrical connector, and wiring already available.
EF/EL Futura Models, and GLi Models with ABS fitted will have this connector already fitted, and wired up, so all that is needed is to add the Low Washer Fluid Switch, which is part of the Windscreen washer Bottle.
The Windscreen washer Level sensor is a simple On Off switch, and is integrated within the Washer Bottle, using a rubber grommet. The sensor can be removed and fitted, but you would probably find that it is easier to simply purchase a new/used Bottle with the sensor already fitted, from a Fairmont, Fairlane or LTD.
The electrical connector is a Female T piece, and is exactly the same type as used on the Front Turn signals.
This piece has 2 wires coming from it, 1 wire is connected directly to ground (Black), and the other wire goes to the Instrument Cluster Right hand side connector. (Pink/Yellow wire)
(See below for Wiring Information, in regards to the Right Hand Side Instrument Cluster Connector).
As mentioned above, when the Windscreen washer level drops to a low level, this switch conducts, causing the Pink/Yellow wire going to the Cluster to be grounded. The Instrument Cluster will then illuminate the Warning segment, on the LCD Panel.
