How to Hook Up a Stereo to a 1988 F-250

In 1953, Ford shook up its F-series lineup with a redesign and a new naming system F-100, F-250 and F-350. The 1988 F-250 had an engine to meet nearly any buyer's needs. The five engines available were: a 4.9-liter in-line six-cylinder, a 5.0-liter V-8, a 5.8-liter V-8, a 7.5-liter V-8 and a 7.3-liter V-8 diesel. Also available on the 1988 F-250 was an optional AM-FM stereo system. Installing a new stereo in the 1988 F-250 is a straightforward task that most owners can complete successfully.
