I got a d-104 here with only 4 wires. dont know if its old or new cause i bought it used. has a silver eagle head on it but it probably wasnt a silver eagle cause all those ive seen are 6 wire. anyhow, the wires are yellow-black-red- and there bare sheild. doea anyone know the color code.????? all the 4 wire d-104s ive seen talked about say they have a white wire. mine dosnt,it has a yellow. plus the red,black and sheild.
