Del Sol

What is the red wire w/ black stripe on my 1995 civic del sol radio harness for?
I am doing a radio swap on a 1995 Honda Civic Del Sol and it already had an aftermarket radio in it. I have looked at Installdr already and it doesn’t list any red wire with a black stripe. What is also confusing is that it has a brown wire with a white stripe for 2 different things. Does anybody know what this wire is for?
Thanks
it is the illumination wire. Thanks
Check the red wire with black stripe for voltage when headlights are turned on. I’m showing it as the illumination wire.
Don’t know about the brown wire with white stripe. I show it as rear left speaker negative, but only one. I also show a brown wire with black stripe as front right speaker negative.
edit. I just looked at the Installdr diagram. One brown with white stripe should be paired with the red with yellow stripe to power the right rear speaker. If you touch these two wires to a common AA battery, you should hear a pop from the R/R speaker.
The other brown with white is shown as the power antenna trigger by Installdr, but my notes show the trigger wire as yellow with white stripe.
