1985 Toyota Celica Supra

im looking for the stereo wiring schematic for a 85 celica supra,  the one on here in the database does not match the wiring in my vehicle.  i also own the toyota maintenance manual for the vehicle but the schematic is very difficult to understand and doesnt go into much depth in the stereo.   If anyone could help me out please do not post but Email me at JustinHegenbart@yahoo.com .  It would be greatly appreciated.

PS - All i know is the front and rear speakers are Brown with different colored stripes, which doesnt match the schematic in the data base there are also several other wires which i am unclear on where they connect.

Thank you.

oh and by the way, i need to know the wires coming OUT of the stock tape deck, not the actual speaker wires themselves like i said the front and rear speakers are all brown with various stripes on them and there is a yellow wire with a blue stripe that is also a mystery to me...

thanks.
