GENERAL CABLE & WIRING INFORMATION:
Running cables will require the removal or partial removal of interior trim panels in your vehicle. All system component grounds should be connected to the same location (this will help prevent unwanted engine noise). The + 12 volt power for all system components can be made at the fuse block using an “add-a-circuit fuse” which can be purchased at a local auto parts store. The “add-a-circuit fuse” is an easy way to add an additional fused circuit without cutting into any wires. A five amp circuit should work for most systems. Disconnect the vehicle negative battery terminal before making any power connections.

HEADREST LCD MONITOR A/V CABLE:
The A/V cable gets run from the LCD Monitor to the video source. One end of the A/V cable has a DIN connector that plugs into the short A/V cable that comes out of the LCD Monitor. The other end has RCA connectors for left/right audio and video that will connect to the DVD,VCR or game. The video input may be located on a small junction box attached to the A/V cable. Depending on the application and monitor the audio cables may not be used. The red and black power wires in the A/V cable get connected to a switched 12 volt source. You may want to add a connector for the power leads if your seat is removable.

INSTALLING LCD MONITOR INTO HEADREST:
Note: You may want to practice on a headrest obtained from the junk yard before you cut your headrests.
1. Installation will vary from vehicle to vehicle – headrests are not standard - the following installation is just one example.
2. The LCD Monitor kit consists of the LCD screen assembly and headrest mounting housing.
3. To release the LCD screen from the housing, slide the flat plastic key on each side of the monitor between the monitor and the housing. If the plastic release key is not included with your monitor any thin flat tool will work.
4. To install the LCD monitor into the housing insert the LCD screen into the housing and press on the edges until the clips click into the locking position. Do not press on the LCD screen.
5. The vehicle headrest will have to be cut to install the LCD screen.
6. Remove the headrest and set it in an uncluttered work area. Take appropriate precautions to ensure that it is not damaged during the installation.

The Following Example is a BOSS BV-56M Installed into a 97 Caravan Headrest
 

Make your Measurements: Push on the headrest to make sure there are no obstructions that would prevent installation and to determine, if possible, how deep the metal support bracket is located. Mark the area to be cut on the headrest, use the back side of the housing as a template.

Carefully cut the headrest using a sharp blade. YOU WILL BE MAKING AN “X” CUT IN THE HEADREST AND WILL NOT BE REMOVING THE OUTER UPHOLSTERY MATERIAL. DO NOT CUT THE SIDES, TOP OR BOTTOM.

Start your cut ¼” from one inside corner and cut diagonally across, stopping ¼’ from the other corner. Repeat the procedure for the other two corners. You will end up with an “X” CUT in the template area. DO NOT REMOVE THE HEADREST OUTER UPHOLSTERY MATERIAL AT THIS TIME. The material will trimmed and folded back in for final installation after you remove the foam.

Carefully peel back outer covering and start removing the foam inside the headrest. Cut to the depth required for the headrest housing you have. Stay 1/4'” inside from the edges and remove just enough foam so that the housing will fit snug. Insert the housing during the cutting to measure the fit and make adjustments as required.

Trim headrest outer covering material, leave 1/2" to 3/4" material around the edge to be folded in when the housing is installed. In this application the headrest foam was removed down to the metal bracket because the bracket was only 1/2" deep into the headrest.

Secure the plastic housing to the headrest using screws through the metal support. Drill holes in plastic housing if required. Drill a 3/4" hole in the metal support to allow the A/V cable to pass through. NOTE: if the metal support is deeper into the headrest you may not have to drill a hole for A/V cable.

Make a small cut in the bottom of the headrest next to one of the support shafts. Pull A/V cable through housing and through hole in bottom of headrest. Install Monitor and conceal the A/V cable using split loom tubing or tie wrap to shaft.

The A/V cable will have to be run through the seat back and out the bottom (running the cable through the seat back will vary). Secure the A/V cable so that it does not interfere with seat adjustment. Connect A/V cable to video and power source. If the seat is removable you can add a connector for power and ground wires so that the A/V cable can be unplugged allowing the seat to be removed.
