Well, I'm afraid this may come as a let down!
I did not expect the guesses that I received regarding my switch panel, and now I feel as though I may have raised everyone's hopes to a high level only to let you down! I hope this is not the case, but if so, I am truly sorry!
My truck was broken into about six months ago and the stereo was stolen. The criminals left a gaping hole in my dash and all of the wires were torn up and left to hang! Anyway, I left it just as they had up until the day of my last post, on that day I decided it would be nice to have a stereo of some sort. Having recently purchased a 30Gb iPod Video, I thought it would be cool to be able to just plug that in and listen to my music. Since the criminals were kind enough to only steal my head unit and leave me my amp and speakers, it was quite easy to get the iPod working through my speakers. The two inputs (which, I must admit, do look much like coaxial inputs) are actually Left and Right RCA jacks, I can plug my iPod into them and then flip the last switch in the panel to activate my amp and, "Viola!", beautiful music fills my cab. Now, currently the rest of the small switches do nothing (the wiring was torn up on them as well), they were used to turn on external lights and such! I had three pairs of rock lights and some reverse lights. Now, ONLY the last of the small switches works. The large red switch turns on my AC compressor because the factory switch went out and I needed a quick fix. Anyway, as I'm sure you can tell, this was a cheap and quick way to get some music into my truck and improve the looks slightly, nothing spectacular, but much better for me!
