This picture shows how the cable is composed. Work backwards using this diagram to build your cable. If your monitor has a 9 Pos. D-SUB connector or a DIN connector. The diagram illustrates a D-SUB. For your source of wire or cable, the easiest method is a monitor extension cable specific to your monitor because the monitors end jack is already on the cable! Just chop off the opposite end and expose the wires by trimming back the cables rubber coating about 1.5 inches or so. Leave the cables wire shielding strands connected, but unweave them. For the monitor end, if the jack was removed, divide them in half and twist together like a girls "pig tails". These should be longer than the RGBS wires in order to reach the farther away outer terminal plate. For the Genesis/MD end, you only need 0.5 inches of shielding that will be folded back to run down the cables outer body. To find the right length of the RGBS and ground wire to solder to the Genesis/MD connector, just eye up the length so that when placing the connector at the end of the cable, you have enough room to solder the wires and attach the outer shielding clamp to the cable (it also secures the connector to the cable). If you left the cables plug on the cable, you will want to know where each wire on the genesis/MD end exits with respect to each pin out on the cables monitor end. Generally, a red, green and blue wire carries their respective signals, and a black wire carries the comp sync..
To test each wire, use a battery and LED or small bulb to do a current flow test. Have one external wire run from the batteries (9 V etc) negative terminal to the LED's negative post. Then attach a unknown cable wire to the batteries positive terminal. Next stick the LED's positive post into a pin out whole until the light comes on. Mark down each wires output to its corresponding pin. Connect the Genesis/MD's RGB output to the monitors RGB input via cable. Thus, solder the red, green, blue, comp sync, and ground wires of the cable to their corresponding output pins on either side of the cable (or one end if the cables monitor jack original). ALWAYS use heat sink tubing if their is a chance any wires will cross. Remember to slide them over the wire before you solder! For the composite sync., a resistor of 470 Ohms ( Radio Shack sells them in packages of 5 for 50 cents) is needed. Trim the resistor ends down to about 5 mm in length. Solder the wire to one end first, then slide the other end into the connectors solder post and solder in place. NOTE: the composite sync should be the first wire you solder to ensure plenty of room to maneuver the soldering iron (other wires get in way). It is not necessary, but attach the the shielding on both ends to their respective "added" connectors. For the Genesis/MB end, fold back the shielding wires along the body of the cable and crimp the copper shielding post around them....which also secures the jack to the cable. On the monitor end (if one was added), connect half of the shielding to ground pin 2 (or pin 1 if the cables ground wire is using 2) and the other half (or lead from it) to the outside metal shell. This acts as a ground and reduces RF interference.
If you are interested in Audio too, basically use a CD players patch cords and cut off one end. At either end of the cable, solder the patch cords shielding to the RGB cables ground or shielding, and the center wire (mono...1 wire) to the corresponding audio output pin in the case of "at the genesis/MD end, or to the extra wire that was used to carry the audio signal from the Genesis to the cables monitor end. Secure patch cord to cable with heat sink tubing before connector is attached, or after with electrical tape etc.
Without audio (use systems headphone jack):
Cable must be shielded, contain 4 wires for R, G, B, S, and ground.
With Audio:
Cable must be shielded, contain 5 wire (6 if stereo or dual mono) for R, G, B, S, ground, audio
