Note If your installation will require you to cut out the headliner the box that this kit came in can be used as a template You can remove the shelf that the video monitor rests on and trace the opening onto the headliner for cutting FULL SIZE CONSOLE INSTALLATION There are several full size custom consoles available for selected vehicles Some of these vehicles are the Chevrolet Suburban Ford Expedition and Dodge Durango These full size consoles incorporate several additional features and are particularly useful if the vehicle you are installing this system into already has an OEM overhead console in the headliner Refer to the installation manual that comes with the console itself for complete installation instructions MINI CONSOLE INSTALLATION This page only covers special installation considerations for the mini console installation If the video monitor is to be installed with a custom full sized overhead console refer to page 3 If the video monitor is to be installed in a vehicle with the mini console P N 102D3595 this console may need to be trimmed to fit the contour of the vehicle headliner 1 In this installation the video monitor is mounted directly to the overhead cross member in the roof using the mounting screw bosses These screw bosses should contact the cross member di rectly i e no gap between the screw boss and the roof structure Also be sure that the screws do not pierce the outer roof skin

7. ON APPROACH Decide upon system configuration and options that will be installed i e what components VCP Tuner RF Modulator external amp remote headphones 2 VCP etc Review all manuals to become familiar with electrical requirements and hook ups Decide upon mounting locations of all components and method of mounting Prep the vehicle by removing any interior trim necessary to gain access to vehicle s wiring as well as all areas where interconnecting wire harnesses will need to be located If any access holes need to be cut into the vehicle headliner other trim Components etc this should be done now as well Refer to Page 3 Route the wiring harnesses throughout the vehicle as necessary Refer to the Wiring Diagrams on pages 6 and 7 of this manual as well as the wiring instructions for the individual components and accessory options being installed Be sure that all wiring is protected from sharp edges and is routed in such a manner that it will not be pinched when all components and interior trim are fully installed Be sure to leave enough slack in the wiring at each component to allow working room Remove all A V system components from their packaging and place them loosely in the vehicle at their respective locations Connect all components together electrically and verify proper operation of all system functions Note This is best done BEFORE components have been permanently mounted After verifying proper operation o

9. inate the bulbs To determine which system you have you must locate the wires at the dome light On a positive switched system with all the doors closed and the lights out both wires at the dome light will rest at ground When the light is activated one of these wires will switch to 12 vdc This is the vehicle s switching wire On a negative switched system with all the doors closed and the lights out both wires at the dome light will rest at 12vdc When the light is activated one of these wires will switch to ground This is the switching wire For positive systems connect the purple brown Lamp auto wire to the vehicle s switched wire Then connect the red black lamp on wire to a fused constant 12 volt source and the black red lamp common wire to a good ground Positive systems are commonly found on Ford vehicles For negative systems connect the purple brown Lamp auto wire to the vehicle s switched wire Then connect the red black lamp on wire to a good ground and the black red lamp common wire to fused constant 12 volt source Negative systems are commonly found on General Motors and import vehicles Note Some vehicles which incorporate transistorized control of the dome light circuit such as the 1999 Dodge Caravan may require that the purple brown Lamp auto wire be connected to the door pin switch wire as the additional current draw of the Monitor s lights may not be supported by the output of the vehicles

11. when fully fastened to the cross member The mini console is attached to the video monitor using the perimeter screw bosses It is important that the screws used in this installation are not overtightened and that the video monitor and mini console are mounted in such a way that the assembly does not distort or bend when the mounting screws are tightened An alternate method is to use a piece of plywood 5 x9 x3 4 First secure the plywood block to the cross member then screw the monitor into the plywood See the drawing on page 5 It is best to mount the video monitor to the roof structure without the mini console first There should be a gap between the headliner and the outer flange of the video monitor The mini console should be cut to full this gap Apply masking tape to the outer surface of the mini console in the areas where the cut will be made Mark the cut to follow the necessary contour of the roof The suggested method of marking is as follows A First mark the narrowest point of the mini console on the masking tape Be careful to consider not only vertical location but fore aft location B Using the handle of a screwdriver make a transfer marking tool See diagram below Place the tool against the roof and the marker against the masking tape on the mini console Trace the cut to be made around the entire perimeter of the mini console C Cut the mini console using a sharp utility knife or shears Make the cut in several
