    The stock wiring harness is intact and in good shape. Just behind the drivers seat mounted on the wall is a factory installed rear passenger stereo control consisting of two headphone jacks each having individual volume control and one power button for sound supply on or off to rear speakers. All schematics I can find correctly identify the front speaker but I have not been able to find any schematics identifying the rear correctly.I have and single color pale pink or maybe flesh color or it could be a beige color wire, red/black, pink yellow, orange/brown, and brown/orange. I have been working on this on and off for over a year and although I have managed to get all working at the same time sometimes it is evident that they are correctly connected as any amount of volume will result in either front or rears crapping out or cutting out. The level of appreciation I would have for anyone who can supply the proper wiring information for these 1989 Aerostar speakers would be immeasurable. I am able to power up the stereo and enable two front speakers correctly by following available schematics. For the rear speakers I have remaining in the dash the following: a solid fleshy tan type color wire, orange/black, pink/yellow, red/black, brown orange. At the rear radio control the plug in consists of 2 rows equaling 10 pins: 1.black/white 2.solid fleshy tan type color 3.pink/green 4.pink/purple 5.pink/yellow 6.orange/black making up the top row. Row #2 situated under pins 1,2,5,6 respectively are 7.red/blue 8.black 9.brown/orange 10.red/black. It is my wish to retain the rear radio control with-in the circuit.
