[. . . ] 3) Decide upon mounting locations of all components and method of mounting. 4) 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. 5) Route the wiring harnesses throughout the vehicle as necessary. [. . . ] Also, be sure that the screws do not pierce the outer roof skin 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 (12"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 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". 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 miniconsole. C) Cut the mini-console using a sharp utility knife or shears. Make the cut in several passes over the marked line, each time cutting a little deeper. It is not necessary to cut completely through the plastic, the cut only need be over 50% of the wall thickness of the plastic. [. . . ] 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. For positive systems, connect the purple / brown (Lamp auto) wire to the vehicle's switched wire. [. . . ]
