Re: Hellllpppppppppppppp Reply #6 – August 31, 2005, 09:26:49 PM on the 84 im not sure if its on the distributor or not. if it is, its a large plastic piece with a wiring harness attached to it. it might be on the driver side fender as well, if so large metal box (grey in color) with Ford EEC number on it and a whooper sized harness Quote Selected
