User manual AUDIOVOX MM701 INSTALLATION

[. . . ] (Refer to the Wiring Diagrams on page 8 and 9 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. [. . . ] The trim ring 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 trim ring 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. It is best to mount the video monitor to the roof structure without the trim ring first. There should be a gap between the headliner and the outer flange of the video monitor. The trim ring should be cut to full this gap. Apply masking tape to the outer surface of the trim ring 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 trim ring on the masking tape. Be careful to consider not only left-right location, but fore-aft location. B) Using the handle of a screwdriver, make a "transfer marking tool". 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 trim ring. C) Cut the trim ring using a Dremel Tool. D) Check the fit of the trim ring and make any minor adjustments necessary. The trim ring can be painted or covered with a material that matches the headliner before assembling the trim ring to the video monitor. The finished trim ring should be attached to the video monitor, then attach the assembly to the roof. 2) 3) Installation Guide 4) 5) Headliner Cut Line Lowest Point Mark Figure 6 Tape marker to screwdriver starting at your mark for the lowest point, then trace the contour of the roof Headliner Cut line Lowest point mark Refer to Fig 7 for detail on attaching console to video mark Tape marker to screwdriver. [. . . ] 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 violet / brown (Lamp auto) wire to the vehicle's switched wire. [. . . ]
