So...My radio started acting up the other day so I pulled it out and started confirming the wiring. Whoever wired it before I had the car made a mess of things it seems. So....I've traced a wire that I believe they may have been using for the radio light. It's a light blue wire with a red stripe and it has a red female connector (see attached diagram) . I traced it to what I believe to be the interior lighting main disconnect at the firewall, but it goes nowhere in the engine bay. My thoughts from the diagram below is that it's the console's shifter light, however, I'm not convinced it's wire '19' as I believe wire 19 is a dark blue wire with a red stripe. Also, I can't seem to get any voltage out of it. I tried the key on, accessory postion, and headlights on. Nothing.
