Assembly guide
Before assembly, study carefully whole the Assembly guide. Switch the ignition off.
Layout of separate parts of the system is obvious from the picture CONNECTION INSIDE THE CAR.
1. Installation of sensors
IF YOU INSTALL SENSORS INTO A METAL BUMPER, YOU HAVE TO USE APPROPRIATE
ADAPTERS (ACCESSORIES).
•
Conditions for layout of sensors in bumpers are in the picture. Choose suitable type of brackets and mark
centres of the holes. For brackets (9) drill holes ø18mm, for brackets (11) and (12) holes ø24mm.
•
Paint the sensors, perhaps even brackets (11), (12) according to the colour of a bumper. Use preparation (19).
Before painting, apply suitable primer for plastics or Primer (15).
•
Apply Primer (15) on the brackets (9). Get it dry for at least 1 minute. Stick the bonding tapes (10).
•
Before sticking of the brackets (9) to the bumper clean surroundings of the holes and lay Primer (15). Get it
dry for at least 1 minute. Place the sensor into the bracket, remove cover foil, insert sensor into the hole and
press bracket fast. Adjust brackets so that connector of sensor comes out horizontally.
•
Place the green sensors into the front bumper, blue sensors into the corners of the rear bumper and black
sensors into the centre of the rear bumper.
2. Installation of the cabling
•
Place the cable box of the front cable harness under the dashboard and pull the cables of sensors through the
engine area into the front bumper. Join sensors along the length of the cables. Join black-blue conductor to
the voltage +12V switched by ignition key. Join brown conductor to the chassis of the vehicle. Join black-
yellow conductor to the signal of speed indicator. Adjust number of pulses per 1 m after accomplishment of
the assembly (see chapter Adjustment of parameters). Join grey-red conductor to the input MUTE of audio.
•
Place the cable box of rear cable harness in a boot and pull cables of the sensors through to the rear bumper.
Join sensors along the length of the cables and according to distinguishing colours. Join black-blue conductor
to the rear light. Join brown conductor to the chassis of the vehicle.
•
Conduct link cable to the front cable box. Mount contacts into the front cable box:
Red-yellow conductor pos.17
Brown conductor pos.5
•
Stick the speaker onto the suitable place under the dashboard. Mount the contacts of the speaker’s cable into
the front cable box:
Yellow conductor pos.15
Blue conductor pos.3
•
Place main control unit under the dashboard so that operating buttons and display are accessible. Join cable
box of the front cable harness.
•
Place rear control unit on suitable place in a boot and join cable box of rear cable harness.
