T4, T5 (2003-2010) 7.8.1

13. Using the tester, we find the wires we need and solder them to the feet connector according to the table.

There are 2 ways to connect CAN bus wires. Choose what is convenient for you.

	1-st way: solder the wires to to the pins of the green connector	2-nd way:  solder the wires to the points, indicated in the photo

2.5 Important! 

If you have  noFIS or halfFIS dashboard, you need to solder the wire from  36 pin of MFD board to the LED`s cathod, on the dashboard.
And you need to remove 3kOhm (302 or 3001) resistor from 36 pin of MFD board.

2.6 Lay the wires in such a way that they do not interfere with the installation of white Light diffuser. 

To connect the ambient temperature.

Resistor at 3 kOhm on the back of the board above the motor of the fuel arrow

You need to remove a 1.5k? resistor to the capacitor — on the input line to the Large IC with a bunch of legs (on the front side of the board under the right side of the tachometer scale)

The capacitor rating should be 10 nF

Those. in order for the assembly to show the temperature overboard on the instrument 

with 3DColorMFD installed in the instrument without MFA (half or full screen), it is necessary:
1. Solder a 3k? resistor
2. Replace the 1.5k? resistor by the capacitor on the input line to the microcircuit
3. Fix dumping device — turn on the temperature input in the eeprom. 

The dashboards are different for T4, so if it’s the same type as VWK501, it’s enough to change:
address 0x178 — value 00 to 01
address 0x1E5 — 2B on 2D

Do not solder these wires! Pins 6 and 7 are spare.

 

	3.1 Cut off Red USB wire, we don`t need it.	3.2 USB cable should be fixed with glue.

To display open doors on T4, you need to lay the wires from each lock into the cluster connector.

If you are the lucky owner of Passat B5, released for USA market, you have to add a few SMD resistors to the dashboard.

There are two types of power supplies

    
Attention!
Before installing the power supply, you need to solder the wires to its contacts IN+, IN- and OUT+, OUT- ,
then apply a current of 12V to IN+, IN- , and connect the OUT+, OUT- wires to the multimeter.
Now we need to tune the output current. Using a small flat screwdriver, you should rotate tuning resistor
clockwise, until you have 5.5V output voltage on the multimeter.
Next, we place the power supply on the cluster`s back board and bring wires from the blue connector to its contacts.
How to do this, look at the connection diagram specifically for your car model.
 

Choose the installation location of the power supply so that it does not interfere later in the assembly. For example:

Attention!

After wiring, lay it so that they do not interfere with further assembly.

Need to  call all contacts and check on the table to avoid confusion anywhere.

2.9 Before assembly, check the functionality of the module in your car.

3. Assembly

On the display, at the back, there is a piece of double-sided tape (if yours doesn`t have it, attach one). Don`t remove the protective film from it! We use it only as a support for the display!

 

	4. IMMO 2  If you have a 1J0 comfort unit installed. Or your car is Seat Leon 1M. Be sure to stretch the wires from the comfort unit to the cluster. The comfort block 9 -> 8 pin of cluster`s outputs (CAN-H Comfort) of the green connector. The comfort block 6 -> 9 pin of cluster`s outputs  (CAN-L Comfort) of the green connector.

4.1 IMMO3 Cluster Installation in a vehicle with IMMO2
If you are installing IMMO 3 cluster in a car with 1J0 CCMS (comfort unit) — you shoul remove 2 resistors from the cluster board.
These resistors are coming from 8 and 9 pins of the green connector.

 

4.2 If you are Installating IMMO3 cluster in a vehicle with IMMO2,

you should activate the ambient temperature sensor in the cluster`s EEprom.

Passat B5 You need to change 1ef from 08 to 01 line 0001E0 column F

Golf 4 Cluster 1J0920806G no fis no show temp in dispay You need to change 1e5 from 2B to 2F line 0001E0 column 5

 

Change 2B in 2F and work

I changed that one 1E0 column 6 from 2B to 2F and it works

 

5. BOOST

To connect the boost pressure control, You need to add pin 15 to the green connector.

The other end of the wire must be connected to the engine ECU.
According to the table below, you should find the signal wire of the boost sensor.
When the engine is idling, the voltage on the wire should be between 1.6 and 1.9 volts. 

With an increase in RPM (engine speed), the voltage on this wire should increase.

 

Most often,

On diesel engines (AVB and others):
— 71st pint of ECU, green — red Wire (green with a red stripe);

On petrol (AWM and others):
— 101 pin of ECU, gray — blue wire (gray with a blue stripe).

In general, as I know, in all B5 diesel 1.9Turbo, supercharging is connected to the 71st pin,

And the gasoline 1.8T is connected to the 101 pin. The color of the wire can vary depending on the year / engine.

6. ASSEMBLY

Collect everything in the reverse order, without forgetting to calibrate the needles with the help of the VAG-com program.

	6.1 To do this, connect cluster to the car  (without cluster glass) and connect it with VAG-com.	6.2 Go to unit-17.
	6.3 Select Test unit.	6.4 Make a needle test. Choose in turn: tachometer, coolant temperature, fuel level and speed . The needles will make a turn on the whole scale, and then freeze. Remember or make a photo of difference in readings. Click «Done» and exit from the unit. Turn off ignition, remove the key and set the needles to correct position, turning them back counterclockwise.
