Hi Derek!The pins in a DIN-Connector should be numbered from 1 to 5 (on the plastic). The easyest to find is the "2", it is the pin in the middle which is ground of left and right together, then "5" = right = red wire and "3" = left = other color. The pins "1" and "4" are record out. If the pins are not numbered, you can find out the wanted, when you plug it in (just the plastic with the pins) and switch on AUX at low volume. Then touch the pins with a piece of wire, one after the other, it's not dangerous! When you hear a humming sound, that's the right. If you want to take care of your speakers, you can use a headset. Have fun! Chris
