For the record, there are two "gray" wires. The thicker gray wire is for the radio front left negative. The thinner gray wire is for the illumination. They look exactly the same and this became a nightmare on my 83 regal when throwing in the Alpine.

[88hurstolds]

Yes but they are on different sets of plugs and the speaker wires are molded together in pairs.

Got it done, Thank you guys!
