you need the metra harness 70-5513. you only use the larger plug on it and cut off the other. it plugs into the amp harness that goes directly to the speakers. just wire it to the deck and its long enough to reach from where the plug is to where the new radio is. that is what i did when i installed my g/fs stereo in her 2000 mustang. the factory amp sucks!
