Controller of the Central Door Lock 

1. Positive pole of the power supply (12V) is connected to the positive  pole of car’s battery through a 15A fuse; when the

engine is started, the voltage is not less than 10V. 

2. Output of the central door lock. The unlock cable connected to the executor of the central door lock is usually grounded

through the normally-closed contact of the internal relay; when the door is unlocked by the remote controller or unlocked

instructionly, the public contact of the relay will get through with the normally-open contact, realizing an output of 12V

voltage.  

3. Output of the central door lock. The lock cable connected to the executor of the central door lock is usually  grounded

through the normally-closed contact of the internal relay; when the door is locked by the remote controller or locked

instructionly, the public contact of the relay will get through the normally-open contact, realizing an output of 12V voltage.   

4. Key detection cable. This cable is connected to the ignition lock of the car and will get through with the grounding wire

when the key is inserted into. (negative input) 

5. Right direction indicator. The cable is connected to the positive pole of the right direction indicator of the car; an output of

12V voltage will be available when this cable is at work. 

6. Left direction indicator. The cable is connected to the positive pole of the right direction indicator of the car; an output of

12V voltage will be available when this cable is at work. 

7. Negative input of door switch, which is connected to the door switch of the car; this cable will be earthed when the door is

opened. (Interior lights will be on) 

a.  Open the door and then close it, the reading light will be on for 10 seconds; if during this period, it is detected that the key has

been inserted into the ignition lock or the door closed, then the reading light will turn off.   

b. When the key is pulled out of the ignition lock, then reading light will turn on, during this period, if the key is reinserted into

the ignition lock or the door lock, the reading light will be off; if there is not any action when the door is closed within 1

minute, the reading light will automatically turn off. 

8. ON power supply detection cable. A conductive wire connected to the ON gear of the ignition lock. (When the key is turned

to the ON position, a 12V output will be available) 

9. Car speedometer detection cable, which is connected to the detection cable of car's speedometer. (When the car is

accelerated to the speed of 15km/h, the instruments unit will output a 500mS rectangular positive pulse to the central door

lock controller, which will control the locking of the central door lock when this 500mS rectangular positive pulse signal is

detected by the controller.) 

10. Output of window closing signal. When the door is locked by the remote controller, this line will be available with an

output of 12V positive current for one second and then be off. (No output) 

11. Locking signal. The locking signal line connected to the central door lock of car's left front door is connected through with

the grounding line when at work. (Earthing) 

12. Unlocking signal. The unlocking signal line connected to the central door lock of car's left front door is connected through

with the grounding line when at work. (Earthing) 

13. Negative  pole of the power supply, which is connected to the car body, (earthing) line shall be as short as possible,

over-length will produce the interference. 

Function of controller of the central door lock 

1. Locking. When all the car doors are closed, press LOCK button of the remote controller once, at this time, the direction

indicator will flash once and the central door lock is closed. 

2. Unlocking. At the locking state, press UNLOCK button of the remote controller once, at this time, the direction indicator

will flash two times and the central door lock is opened. 

3. Car-finding function. At the locking state, press LOCK bottom of the remote controller once, and at this time, the direction

indicator will flash ten times quickly. Press UNLOCK button of the remote controller to quit the car-finding function. 

4. Automatic prevention function. At the locking state, press UNLOCK button of the remote controller to open the lock; if the

CD Player and Air Conditioning System-2

CD Player

Function Overview

This product is a kind of car audio system with VFD multi-information integrated display screen with such functions as PLL

electronic tuning radio, CD playing and operation & control of air conditioning system, it can receive AM, FM and FM stereo

radio broadcast programs, play CDs, electronically operate and control the air conditioning system of the car. The integrated

display screen can display the working state of the radio, CD player, air conditioning system, operating mode as well as

information concerning the equalizer, clock and the temperature inside and outside.

Wiring Instructions(see the diagram)

with the speakers: the amplifier of main unit of this system is designed with 4-channel BTL output, each speaker must

be wired individually; the phase position and place of the speaker must be connected correctly; please disconnect the

player from the power supply before connecting the speaker so as to avoid the short-circuit.

2. Connecting main unit with the integrated display screen:

Use the specially-supplied 12-pin connector cable to connect the VFD integrated display screen and main unit.

3. Connection of power supply, output and communication line of main unit:

At first, connect the communication cable of the 20-pin connector plug to the air conditioner ECU, then connect the speaker

output line to other lines, finally connect the yellow memory power supply cord (10A fuse tube) directly to the positive role of

accumulator; when all the wiring is completed, connect the red power supply cord (1A fuse tube) to the positive power supply

of the ignition lock.

4. Connecting main unit with the antenna

Typical antenna: insert the plug of coaxial cable of car’s antenna into the antenna socket of main unit.

Automatic antenna: insert the plug of coaxial cable of car’s antenna into the antenna socket of main unit, then connect the blue

antenna control cable in the 20-pin connector to the automatic antenna control end, connect the positive pole line of power

supply of automatic antenna to the positive pole of accumulator and the negative pole line to the earth.

5. Connecting main unit with CD-change box

CD player and the CD-change box are connected with the signal cables.

 Prior to the installation, please be sure to remove three protective screws on the CD-change box and have it pasted with

ant-dust paper. If the protective screws are not removed, CD can not be played normally.

Attention: Improper wiring may result in the damage to the player!
