Installation Procedures
Remove the headliner from the vehicle for installation.
1
  Remove the interior headliner from the car in which the unit is to be installed while taking care not 
to damage the interior or its fi ttings.
2
 Now remove the dome light but leave its wiring in place.
5
  Use the tool such as a power drill to drill holes 
in the ceiling reinforcement crosspieces to meet 
the mounting holes on the assembled plates.       Caution: 
≥  Before drilling the holes, check exactly 
where the unit and bracket are to be 
installed. Take care not to injure your 
 ngers with the power drill or other tool 
you are using. Also take care not to 
damage the ceiling panel.
≥ Wear goggles or protective eyewear to 
shield your eyes from airborne metal 
particles during drilling. Failure to heed 
this caution may result in an accident 
and/or injury.
6
  Affi x the assembled plates to the ceiling 
reinforcement crosspieces securely using the 
screws and nuts.

Note:
≥ Headliner construction and the position of chassis lights vary depending on the type of 
vehicle. Do a preliminary check before starting work.
3
  Decide the position for attaching the base plate 
on the upper and lower slide plates. Attach it by 
screwing in the included screws (5) and nuts 
(7) in 8 positions.
2
  Align the upper and lower slide plates with the 
ceiling reinforcement crosspieces, sliding the 
slide plates as you position them.Note:
≥ Depending on the position of the lower slide 
plate within the range of A or B shown in 
the fi gure at left, screw the upper and lower 
slide plates and base plate according to the 
procedure below.

2
  Put the headliner that was removed earlier back 
in its original place.
3
  In the re-attached headliner, locate the center 
position of the base plate which has been 
attached to the reinforcement crosspieces, 
and cut out the section that will expose the 
reference holes to view.
4
  Align the guide holes in the accessory paper 
template (1) with the reference holes which 
can be seen from the section that was cut 
out from the headliner, and paste the paper 
template onto the headliner using a tape or 
other thing.
       Caution: 
≥  As you cut the headliner, take care not 
to cut your  ngers. Also take care not to 
damage any other areas of the headliner. 
Failure to heed this caution may result in 
an accident and/or injury.Note:
≥ Some cars have a thick headliner, use 
spacers or have other conditions that 
prevent the use of blue ceiling refl ected 
illumination. Before proceeding with the 
installation, contact your dealer and fi nd 
out whether your car allows the use of 
refl ected  light.
≥ Before cutting the headliner, check the 
direction of the paper template to prevent 
any mistakes in the installation position.

5
  Pull out the wires that you pulled from the 
pullout opening of the base plate beforehand so 
that it will be easier to wire.
3
Wire the unit and replace the headliner.
1
  Connect the wiring of the dome light and 
the unit, and bring the wiring as far as the 
installation position.       Caution: 
≥  Pass the wiring you have brought to the 
installation position through the pullout 
openings in the base plate. Take care 
that the wiring is not pinched or caught 
by the top of the base plate. Pullout openings
Base plate top
Note for connecting the dome lights
(page 30s31): 
≥ There are two common types of dome 
light circuits used, positive or negative 
switched. 
  Positive systems supply voltage to the 
interior lights to turn them on, negative 
switched systems apply ground to 
illuminate the bulbs. 
≥ The dome light lead connection varies 
depending on the type of vehicle. Consult 
a service technician as needed. 
≥  Both positive and negative switched 
light circuits are supported by this 
unit’s door switch. If the door switch 
is not wired correctly, the dome 
light will not come on properly.
The polarity differs from one model to 
another so be absolutely sure to ask a 
dealer or service technician to wire and 
install the unit.

Note:
≥ Be careful not to scratch the surface of the 
front cover when removing it.
≥ The screws you remove now will be needed 
when you re-attach it to complete installation. 
Keep them in a place where they will not be 
lost.       Caution: 
≥  Before installing the unit, be absolutely 
sure to check that the screws do not 
make any contact with the ceiling panel.
If some space is required between the 
base plate and the unit, attach and 
adjust the under cover (see next page). 
For details on installing the under cover, 
consult your dealer.

Guide d’installation      MISE EN GARDE : ≥  Utilisez l’appareil dans un véhicule équipé d’une 
batterie 12 V cc avec prise de masse -. Cet 
appareil est conçu exclusivement pour les 
véhicules équipés d’une batterie 12 V cc avec 
prise de masse -. Son utilisation n’est pas 
possible dans les véhicules lourds équipés d’une 
batterie de 24 V cc (tels que les camions lourds, 
les véhicules à moteur diesel conçus pour les 
climats froids, etc.). L’utilisation de cet appareil 
dans de tels véhicules comporte un risque 
d’incendie ou de mauvais fonctionnement.
≥  Assurez-vous d’avoir déconnecté la borne - de 
la batterie avant de procéder au câblage et à 
l’installation de l’appareil. Si la borne - de la 
batterie est toujours connectée au moment du 
câblage et de l’installation, il a risque de choc 
électrique et de blessure suite à un court-circuit.
≥  Contactez votre concessionnaire ou le fabricant 
pour qu’il vous indique la procédure requise, et 
suivez rigoureusement les instructions reçues 
avant de procéder à l’installation de cet appareil 
si votre véhicule est équipé coussins de sécurité 
gon ables et/ou d’un système antivol.
  Des procédures particulières peuvent être 
nécessaires pour le raccordement et la 
déconnexion de la batterie lors de l’installation 
de cet appareil. Le non-respect de la procédure 
à suivre comporte un risque de déploiement des 
coussins de sécurité gon ables ou d’activation du 
système antivol par inadvertance, dont peuvent 
résulter des dommages au véhicule ou des 
blessures.
Remarque :
≥ Les divers réglages qui ont été sauvegardés dans la 
mémoire d’un autre appareil du véhicule (appareil de 
navigation routière, etc.) risquent d’être perdus si les 
bornes de la batterie sont déconnectées.
  Il est donc recommandé de prendre en note les 
réglages ou d’en faire une copie de sauvegarde avant 
de déconnecter les bornes. 
  Une fois l’installation de l’appareil principal terminée, 
réglez à nouveau l’appareil en vous basant sur vos 
notes.
