radio

does anyone know if the 1995 buick century uses the same wiring harness as the 1993 buick le saber?

i have had the speakers make a loud squeaking noise only when i press the gas peddle this dosent happen often but it is usualy fixed by letting the radio sit off for a minute or two what might couse this, or how can i fix this?

The LeSabre and Century do not share many parts at all. They are a different size car with different everything. Wheels, radios, things like that, sure, but a wiring harness? No.

Make sure there are not loose wires under the carpet near the gas pedal. If an idiot wired your stereo, he probably ran the wires under the carpet where they get crushed during daily use.
