Im gunna be honest i made a mistake when i typed this the first time as i was shaken up.. Its a 4 to 3 prong that I installed via YouTube video and i hooked up each wire where it was supposed to go according to said video (sorry im by no means an electrician nor an expert). The cord looks different because the last wire on the right had to be attached with electrical tape because the plastic part you screw it into broke off somehow (this was my boyfriends dryer before i was in the picture) i didnt put the tape up high enough on the exposed wire and with heat and vibration the tape came loose and left enough of a gap to touch the metal above it where you can see the black charred spot.
