Body Electric System

CCL and Electric Rocker Gear System

Definition of the connecting wire of CCL

1. G/R (G/W) Turn lamp

Connected to the anode wire of the turn lamp (right ) on vehicle, it will output 12 V voltage

when it is in operation

2. O

w/b1)

Window-shutting signal output

This wire has one second of voltage output of 12V when the car door is locking. (top SY SJ)

3. No connection

4. G (Y) Unlocking output of CCL

Connected to the locking wire of actuator of CCL, and the normally closed contact in the

internal relay is the grounding wire.It will output 12 v voltage when locking with REMOTE

CONTROLLER or manually because the common spot of relay will contact the normally

opening contact.

5. Bl (G) Locking output of CCL

Connected to the locking wire of actuator of CCL, and the normally closed contact inside

the internal relay is the grounding wire.It will output 12 V voltage when locking with

REMOTE CONTROLLER or manually because the common sots of relay will contact

with the normally opening contact.

6. Gr (G/B) Turn lamp

Connected to the anode wire of left turn lamp of vehicle, it will output 12 v Voltage when in

operation.

7. W (W) Manually controlled unlocking signal

The door lock control the locking process through the manual unlocking switch at left front

door, that is, under the locking condition, press the switch, the lock will be opened (the

switch will return to the connection situation automatically after pressing.

8. Br (R/B) Negative output of door switch

Connected to the car door lamp switch, it is connected to the grounding wire (the indoor

lamp will light when opening the door.

9. R/G (G/B) Rotating speed test

The car door will lock automatically when the vehicle reaches a certain speed.

10. W(R )

ACC test

Connect to the ACC wire, which will have 12 V voltage when the key is rotated to the ACC position.

11. R (R )

Power anode (12V)

Connect to the anode of accumulator on vehicle, in front of which should be set the fuse

so that the voltage will be no less than 10V when the starter is in operation.

12. B(B) Power cathode

Connect to the body (grounding wire), it should be short as possible as can because the

overlong wire will produce the interference source.

Acoustical equipment system

The devices in this series is the vehicle-equipped acoustical receiver and recorder whose function is realized through

the electronic tuner and CD recorder, therefore, it can receive the amplitude modulation, frequency modulation and

stereo broadcast and can record the CD disc, what??s more, it is with the advanced electric anti-quaking, strong capability

of error correction, fashionable blue LCD liquid crystal digital display, and four-way power output. The device in this

series also has the characteristics such as low distortion, large output power and good performance of anti-interference,

broad frequency range and sweet sound, etc.

Mount of bass speaker and VCD

(a)

bass speaker

Connect the audio output wires of bass speaker with the sockets in bass speaker correspondingly according

to the wire color (red plugging element should be plugged in red socket, yellow plugging element in white

socket, the grounding wire (black), power wire (yellow) and signal wire (blue) should be fixed at the

corresponding positions (GND

12V

REM) on bass speaker tightly.

(b)

multi-disc VCD

The feed cables of VCD main device should be connected as marked, when connecting the plugging element

of wire harness of video camera (CAM) with the plugs on main device (CAM), notice should be taken on the

two arrow marks so as to prevent the plugging element damage; The audio output wire plugging elements (red

and yellow plugs) of bass speaker should be connected with the red and white sockets of mainframe (AV OUT);

the plugging elements of TV receiving input wire of amplifier should be connected with either of the plugging

elements(AV AN) of the mainframe; the plugging element (black and white ACC) of anode wire of power

supply should be connected with the red socket (ACC) of mainframe wire harness; grounding wire plugging

element (black GND) should connect with the black socket of mainframe wire harness; the plugs of audio input

wire of deci-disc data converter should be connected with the red and white socket on mainframe according

to the plugs color (the plugs (red, white CD OUT) of audio input wire of eight-disc box should be connected

with the red, white socket (CD IN) on mainframe according to the plug color, the yellow power wire plugging

element (BATT) should be connected with the yellow power wire socket (BATT) on mainframe, the electric

aerial, plugging elements of control wire of function amplifier should be connected with the electric aerial

(CTL), socket of control line of function amplifier on mainframe. After completing the connection of plugging

elements, wrap the connecting position with adhesive strap in order to prevent those plugging elements from

peeling off, the plugging element of feed cable of TV receiving aerial can connect with any two of the four

holes on amplifier, meanwhile, turn on the switch (with a red indicating lamp) of amplifier when watching the

TV play. When mounting the VCD mainframe, push the wire harness innermost as can as possible so that there

is spacious room for mainframe, then push in the mainframe, notice should be taken not to damage the wire

harness. Fasten the mainframe to the degree that it cannot be pull out by hand after assembling, if it cannot be

clamped tightly, prize out the two clips on the inner sleeve, then fasten the mainframe, and mount on the

external decoration frame finally. When disassembling the mainframe, tear down the external decoration

frame first, then insert the special key into the open grooves at two sides to pull out the mainframe.
