How do I wire speaker wires to an after market sterio in a 97 xr7 merc cougar after the original harness has been cut

SOURCE: Wiring Problems

You didn't cut the plastic connectors off the factory wiring, did you? One is gray and one black.... if not, just get to a stereo shop and buy a wiring kit for your car and all colors will match. They're about $10. If you DID..... well..... we have a LOT of work to do....

Hi
have we spoke before in previous post?
the red can go to any 12v live peramanent such as wire to clock or other item that has power with ignition off and the same with the yellow if your putting these to the same permanent live say from clock you can join these to together red/yellow to red on clock
the black can go to any metal or neg wire.
This should then have your device working the only problem im looking at for you now is the pink wire as this stops you using the device whilst driving as it goes to handbrake but i need to find out if its live or negative.
You could just wire the red/yellow to live and black to earth then see if it switches on and works if not then let me know and ill see about the pink wire ok
Makes sure you use inline fuses on the live wires so as not to short the device out.
Make sure you know what is permanent live to put the yellow/red wire to.
It doesnt need to be ignition it only says this so you cant use it with ignition off but you can wire it into any live feed from clock or switches so its up to you what to wire it to its just the pink wire im concerned about.

PINK: does it tell you to put it to live or earth on handbrake switch?

let me know ok

glad you posted what colors you do have , cause 2 resources didn't match ,actually 3 , i did find a match to your colors was a 97 year model premium radio, so we have a match .....

black/ light green = ground
dark green = left front spkr +
purple = right front spkr +
blue/white = right rear spkr -
brown/blue = left rear spkr -
brown/yellow = left rear spkr +
blue/orange = right rear spkr +
black/yellow = park lamps
brown/red = left front spkr -
orange = dimmer signal
pink = fused battery +
green/red = radio choke relay
red/white = fused ignition
blue/red = right front spkr -
