I have a pair of J&M lower hook up cords that I used with headsets purchased in 2003 for my LT (don't remember the model of headset, but you can research that). One is for the Elite headset with a half-moon connector to the upper cord (label on cord reads "HZ"), the other is the "P" cord for the Performance headset (label reads "PM"). They're both 8 pin to six pin cords and plug into the LT comm system (again, this was an '03 LT). They work fine, but I don't need them. I f you need them drop me a PM...
