my output jack died recentlly, im trying to put in the new one but i dont knbow which wires to put where. i have one main grey wire that has a thin white wire that comes out and also has braided metal (wire?) coming out. it was my understanding that of the 3 heads on the output jack the small one is the + and i dont wire anything to that, where do i put the other 2. any help would be much appreciated, ive already melted the carpet, hahah uh oh :(
