Does anyone here know how the 1986 Buick Le Sabre is wired from the head unit to the antenna in the rear corner of the trunk? My antenna has been broken for years, and I recently bought a new one in order to get better reception. I am unsure of the wires that were plugged into the old antenna and have decided to just wire a new antenna wire from my head unit (an aftermarket sony) to the trunk. I want to put the ant wire with the other wires ie left rear and right rear speakers. Is there a way I can find where they are without having to rip apart my car? I am also wanting to know where the wires for the audio system are because I may put an amp in my car later. Any help is appreciated.
