'90 LX - what colour are + & - speaker wires?

'90 LX Coupe. 4 speaker system. Cut the dash speaker wires before I realized I didn't know which wire was + or -. Could someone please tell me what wires are + and - for both the dash and rear deck speakers?

Before you go there, I already know about the speaker wire convertors for Ford specific connections you can buy at Best Buy/Circuit city for like $6!

Thanks.

I have bought but not installed the door speakers or the rear deck speakers yet. When I install the rear speakers I will buy the Ford wire connectors from BB or CC. I have only installed the dash speakers so far.

You have a '98. I wonder how much wire colours have changed from 90 to 98? I found this on another Stang board. This sounds like my wire colour scheme:
------------------------------------------
Right Rear Negative(-) - Green/Orange
Right Rear Positive(+) - Pink/Blue

Right Front Negative(-) - Blue/White
Right Front Positive(+) - White/Green

Left Rear Negative(-) - Blue/Orange
Left Rear Positive(+) - Pink/Green

Left Front Negative(-) - Green/Orange
Left Front Positive(+) - Orange/Green

On wires with dual colors (color1/color2), the first color is the color of the wire and the second color is the color of a stripe running down two sides of the wire.
------------------------------------------

The 12volt link is not working.

My dash wires are colour coded (sitting in driver's seat):
left front - blue w/white stripe and orange w/green stripe
right front - green w/orange stripe and white w/lime stripe

Does anyone know which are positive and which are negative?

For the rears I am going to buy the clip convertors from Best Buy/Circuit City.

Great site! It mentions that Ford does not consistently use the same wire configurations. Just great!!

I checked the stock wiring section, the configuration listed does not match my config. However, I went to a 94-99 install wiring diagram & it seems to match my wire colours! Go figure!

Thanks for the info.
