Ford Escort 1988 radio wiring
 

I just got my grandmothers old Ford Escort 1.3 from 1988 which has the original old stereo inside, which doesn't work anymore.

I have taken the old stereo out while wanting to connect a different one, but I can't seem to figure out the wiring.
I can find all the speaker cables, but the power, constant and those cables arent the same colors as explained around on the internet. (I don't have the option to find which ones hold power and so on)

There is 5 cables:
Brown (thick)
Red (thin)
Yellow (thin)
Blue/yellow (thin)
White/red (thin)

Does any one have these cables in their old ford Escort and know which ones goes where? (I know which cables does what on the radio)

kind regards,

Generally,
Red= hot all the time for clock and to keep memory for stations
Yellow= hot with ign on for power to turn on radio.
The others are probably speaker wires
To confirm that, key off, use a 1 1/2 volt AA battery and touch one of the speaker wires to the positive terminal of the battery and the negative (back) of the battery to ground or the brown wire. You should get a static sound from the speaker when you touch the terminals to the battery and that should tell you which, if more than one, speaker. Again this is generally and should be used only as a guide.
