instrument and tailights affected be stereo

[Firebeast67]

Hey guys, I have an '89 240SX that is buggin me.. I reviewed all 7 pages of posts in the audio section here, and while some topics have been close to my dilemna, none have been identical. I just took out what I assume to be the stock stereo (Clarion radio) and installed a Kenwood cd changer. The cd player works exactly as it should, all 4 speakers work and it sounds fine. However, the lights in the instrument panel, heater panel area, and from what the police just told me, the tailights are all not working. I have found a rough wiring diagram that shows 2 illumination wires, a negative, and a positive that I do not know where to put. Has anyone ever been through this, or have a wiring diagram that I could look at? Any help would be appreciated. Thanks

Does your cigarette lighter work? (seriously) This sounds like a classic fuse problem situation, but get back to me.
