Can anyone tell me if this is the injector? There are some numbers 1E421 and 1E422.
How can you figure out what colors the wires are among these bourgeois abbreviations?
I found it on the Internet, maybe someone needs it
Important terminals: Terminal 15 is powered from the ignition switch. Current flows only when the ignition is on. The wire is usually green or green with colored stripes. Terminal 30 Battery voltage is always applied to this terminal. The wire is usually red or has colored stripes. Terminal 31 is connected to ground. Ground wires are usually black. In electrical diagrams, symbols consisting of a combination of letters and numbers are introduced for individual wires.
Example: 31S - ASZA/1.5 BK/RD 31 = terminal 31 = “ground” (-) S = electrical wire included additionally (not serial) AC = system (AC = lighting range adjustment) FOR = communication: 3 = wire number, A = branch designation 1.5 = 1.5 mm2 VK = main color (VK = black) /RD = marking color (RD = red)
Abbreviations for the colors of electrical wires on diagrams GN = green RD = red SR = silver WH = white VT = violet YE = yellow VC = black GY = gray BN = brown LG = light green BU = blue OG = orange

Ford Focus 3 theft protection is a serious undertaking
Ford Focus is a regular visitor to installation shows. Among the reasons for the frequent appeal are the large number of cars of this model in the city, official statistics on thefts (they are often stolen) and word of mouth. The first surge of “Focus” activity was observed after an unsuccessful attempt to steal one of them belonging to our client, while the car itself was thoroughly vandalized. Owners often know as well as car thieves that there are weak points in the security of this particular model and turn to specialists for help.
This is not the first time the owner of the new 2013 Ford Focus 3 has contacted us - he once entrusted us with the protection of his old Focus. The previous car served its purpose and was sold, and we were tasked with equipping its successor with all the necessary means of protection. Requirements: inexpensive (corresponding to the class and cost of the car), but convenient and efficient.
Due to circumstances beyond our control, the installation was carried out in two stages. The client came to us for the first time to install a hood lock and immobilizer.

Errors in fuse box repair
Many motorists underestimate the importance of regularly inspecting fuses to ensure they are working properly. Homemade fuses are often used. Of course, there are situations when you urgently need to replace a burnt out element. Then there is a temptation to use a homemade or Chinese fuse. This is strongly not recommended as it may damage the original electrical system of the vehicle.
Advice! Often, jumpers or commonplace paper clips are used as a protective element. To avoid short circuits or costly damage inside your vehicle, we recommend avoiding this practice.
It is important to understand that during repairs you need to pay attention to the fuse rating. Let us explain with an example: if a burnt-out PCB responsible for a car charger or cigarette lighter had a rating of 2A, then the replacement should be made with a part with the same resistance value. Ignoring compliance with ratings can lead to more serious and systematic breakdowns.

Before starting installation or repair work, it is recommended to clarify the purpose of the wires using a tester and visual inspection.
How to connect your phone to the radio On cars, the basic configuration does not have an AUX connector and a Bluetooth wireless communication module.
To expand the capabilities of the head equipment, it is necessary to replace the radio or modify the existing device by installing additional components, and installing an AUX port requires reprogramming the radio.
To connect your phone to the radio wirelessly, you need to purchase a Ford Focus 3 ignition switch pinout, placed in the USB port.
The product design contains a Bluetooth communication module, which transmits processed data through a connector. To get started, you need to install the signal converter into the USB plug, turn on the head unit, and then activate wireless communication on your phone or smartphone. The equipment allows you to listen to music, but is not intended for phone calls.
Site Map
Another connection method is to install a Bluetooth adapter model PT, which is connected via the power connector.
The device is mounted on the front panel, the volume level is adjusted using standard buttons on the steering wheel. Malfunctions and their solutions A common defect is the spontaneous shutdown of the radio after 10 minutes of operation with the engine turned off. After starting the engine and supplying voltage to the on-board network from the generator, the radio turns on, but then the situation repeats. The reason is an error in the Ford Focus 3 pinout of the ignition switch on the control unit, associated with prolonged use of the battery.
Instructions for resetting the BMS parameter responsible for battery life: Turn on the ignition, but you do not need to turn the crankshaft with the starter. Press the rear fog signal activation button 5 times successively. After this, press the Ford Focus 3 alarm ignition switch pinout button three times. The ignition system is designed in such a way that the spark to ignite the combustible mixture is transmitted through high-voltage wires.
Below you can find diagrams and designations of the main components.
Like any other car, Ford Mondeo 1, Focus 1, 2, 3, 4, restyling is equipped with a fuse box, the elements of which allow you to protect the car’s electrical equipment from power surges. But in addition to the main power supply, Focus 4, 3 or any other is also equipped with another unit in which relays are installed.

Ford OEM radio pinout
Radio tape recorders installed on Ford cars have always been famous for their reliability, remarkable design and advanced functionality. The connection and pinout of the connectors of standard Ford radios is simple and logical - the connector of these car radios, until 2011, was similar to the connector of premium brand radios - it had a square shape, very ergonomically accommodating several sub-connectors for additional functionality, this connector is called Quadlock. The pinout of all quadlock connectors is similar, but Ford would not be Ford if it had not stood out among manufacturers and added its own special features and additional functions, for example “Anti Theft”, the task of which, as is not difficult to understand from the name, is to protect the radio from theft. And this is not the only innovation of quadlocks from Ford; they also have their own technology for communicating with the CAN - the car bus and a convenient, simplified system for retrofitting the radio with a Bluetooth function. But in cars since 2011 - in the 3rd generation (Ford Focus 3, and other models) the Quadlock connector was abandoned. The new connector has become slightly different in shape, now it is separated from the additional subconnectors. functionality, which are now scattered on the back wall of the radio.
There is probably no Ford car owner who would not be proud of the standard radio in his car. Owners do not often have to turn off and remove the radio, but in principle it is not difficult to do this. If you carefully study the instructions for the car, everything will immediately become clear and logical. In order to connect a Ford radio of any generation, you only need a radio pinout diagram and knowledge of the color indication of the car’s wires in order to understand which wire is responsible for what and what we connect to what. Let's look at both at once:
The diagram shows the pinout of the Ford 6000 CD radio and the color indication of the wiring of Ford cars. Such connectors are used on Ford cars of the last two generations, most often these are the 3rd and 4th generation of brand cars or other recent Ford cars. But we need to look at the connection diagrams and pinouts for car radios of all current generations of the Ford brand.
Pinout diagrams for radios of various Ford models
The article will discuss the radio pinout diagrams for the following Ford models: Focus 1 2 3 4 generations, Mondeo, Fusion, Transit, Kuga, Explorer, Escape, Fiesta, Eco - sport, S-max and other Ford models, both new and old , as well as radio tape recorders 6000 cd, 5000c, Ford - Sony and others.
Ford Focus 3, 4, Mondeo 3, 4, Transit, Kuga, Explorer, Fiesta, Eco-Sport and C-Max of the latest generations (after 2011)
Ford Focus 2, Mondeo, Transit, Kuga, Explorer, Fiesta, S-Max (generations up to 2011, Sony radio, 6000 CD)
Pinout diagrams for outdated radios of Ford models
Next, we will look at outdated and not very, but still relevant radio tape recorders:
Ford 5000C Sony
Ford 5000 RDS-EON
Ford Focus 1, Explorer 2G
Ford Galaxy (Sony)
Ford 3000 Traffic
Some old Ford radios with a CD changer
ISO - adapter for car radios of Ford models
And, if you want to connect a radio from Ford to a car of another brand, you will need an ISO - Euro plug. The adapter will allow you to connect the radio without resorting to cutting wires and soldering the connector, in general, without unnecessary work.

In the article we presented the pinout of the main current connectors for Ford radios. We hope that you have found among the information provided a pinout diagram for the connector you need. We wish you good luck in connecting! Meet us on the pages of our website!
Ford Focus 3 ignition switch pinout
If you diagnose electrical circuits, any short circuits are excluded, since this can contribute to the failure of the equipment as a whole. When replacing fuses, use only parts specified by the vehicle manufacturer.
If the elements are designed for higher current, they should not be used, like any other homemade fuses. To prevent a short circuit when replacing a fuse, it is prohibited to use any metal tools to dismantle and install them.
When the power unit is running, the battery cannot be disconnected, as this will damage the voltage regulator and other components of the electrical circuit. When diagnosing a Ford Focus 3 generator bridge ignition switch pinout, you cannot use a megohmmeter that is powered by more than 12 volts.
In principle, increased voltage is not recommended for diagnosing system components. If you are welding elements of a vehicle body, then to do this you need to disconnect the battery, as well as the generator device.

Replacing the PP in the car interior
The fuse box, which is located inside the car, is a kind of Achilles heel of the Ford Focus 3. If you think that your PP box inside the car has failed, then it’s time to carry out diagnostics. To do this, follow the instructions below:
- Open the hood of the car and disconnect the battery from the power supply. It is noteworthy that to replace or inspect fuses from any section, you need to remove the battery terminals.
- Under the glove box inside the car there is the unit itself. It is not easy to get to it, since it is located exactly under the glove compartment (popularly called the glove compartment).
- The block body is prudently secured with two clamps. To remove them, you need to pull them down at the same time. Once the fasteners are removed, you can remove the plastic cover.
- The fuses are located directly behind the cover. Following the diagram of their location, remove each one sequentially and inspect it. Be sure to replace burnt or faulty ones.
- Use the special pliers located there to remove all the fuses. After removing all the elements, you will see a cable harness. It must be carefully disconnected from the device.
- There are two more fastenings ahead, after which you can completely remove the block from the PP. This completes the preparatory steps. You can begin installing the new fuse box. Be sure to make sure that all previously disconnected harnesses are in their new place.
- After connecting, check the functionality by turning on the cigarette lighter, low and high beam headlights, car lights and others in turn. If everything works properly and there is no wiring smell, then you can close the lid.
The Ford Focus 3 fuse diagram will help you avoid confusion and check the required PPs. A car is a multifunctional system that uses dozens of fuses. When making repairs, carefully study the location of the parts, as well as their ratings. The average power of a cigarette lighter, for example, is 20A. This means that for replacement you need to select a spare part with exactly the same voltage rating.
Advice! If you doubt that you can handle electrical work for the first time, ask a more experienced friend for help. We assure you that replacing fuses the second time will seem like a simple task.
