Making The Indicators Flash with the alarm Originally written by Steve Martin of MEG

This has to be one of the simplest modifications you can do, and takes less then 5 minutes! This only applies to Mk1 mondeos as Mk2 and Mk3 have the system as standard. Unfortunately not all mondeos have the relay holder in place. Fitting these relays will make the indicators flash when the alarm system is activated (Set-off) and also make then flash twice when double locking is set (Unless your car currently beeps to confirm activation)

You need:      

2 Relays

You may need:

• Philips screwdriver
• Socket set

These are the relays that you are after. You can find them in scrapped mondeos - Two are in the engine fuse box (headlights / sidelights) and there is also a single one in the passengers fuse box for the internal lighting. Whilst there, you might find brown or black ones which you should NOT use as they are not designed for the same current.

First you need to locate the mounting bracket - in the drivers foot well, behind the alarm module.

This photo is looking up at the right hand side of the drivers foot well - the black plastic in the bottom left is the top of the accelerator pedal.

• A = This is the lower half of the engine management system's control box (ECU)

• B = This is the alarm/central locking module

• C = This is the "door lock bracket" where the relays will fit.

There may also be a large silver box in front of the alarm module (Radio Amplifier on higher spec cars)

Depending on access you may or may not need to do the first step. It involves removing the lower half of the dash surround (the piece below the steering wheel. Basically there are three screws to remove, one in both bottom corners and a third at the top of the small storage area. Once all three are removed there are two spring clips in each top corner retaining the panel so you need to tug it free. You should now be able to see something resembling the above picture.

The next step it to remove the two gold nuts that hold the alarm module and bracket in place. If you are lucky then they will only be done up finger tight, else you may have to get a small socket set in there (Size 8). The right hand nut is normally hidden behind the insulation foam so just pull it back so you can see it. Once both are removed then you can slide the alarm module off.

With the alarm module off you can withdraw the mounting plate as shown above. The brown socket is for heated seats so you may or may not have a relay in this socket.

Insert a relay in each of the white sockets (ones for the left, the others for the right hand side indicators) With both relays installed you can reinstall the bracket on the mounting pins (Relays should be facing the front of the car), then the alarm module and, where fitted, the radio's amp. Do up the gold nuts and replace the lower dash panel.

The last thing to do is test the indicators flash with the alarm horn. Drive the car to a quiet area where you can set the alarm off without annoying everyone! Put both the front windows down and the get out and lock the car. Watch the dash alarm LED until it stops its rapid flashing then lean in and open a REAR door - the alarm should then go off and the indicators will flash. Reset the alarm by unlocking the car.
