i dont know what you need the information for and this might get me laughed at but screw it
... i never use a wired headset so i just hacked up the one that came with the Mogul and played around with the braided leads until i got what i needed (left+- right +- mic+- and the signal wire for the call/answer button) i made myself a nice little dashboard dock with a cheap universal holder, alot of superglue, and some of that liquid rubber you dip tool handles in XD ..... you slide the mogul into it and it charges the phone, sends audio to the car stereo aux input, and gives me a handsfree mic for calls ..... i guess its kinda ghetto and i had to destroy my OEM headset but it works like a dream .... so easy to pull the device in and out of it .... and you gotta love hoppin in the truck and havin shoutcast bumpin through the subs 3 seconds later
EDIT: its erally easy to find out on your own but if you like i can tell you whats what according to lead color ..
