I replaced my stock piece of junk with a cheap CD player. The wire leads are simple. Make sure to watch the power lead on the ashtray. I didn't have enough wire to rewire around the fader so I wired the front leads from the stereo to the leads off of the fader. Don't try to wire front and rear leads together. Like I said I did this to just get by for now. I installed 5.25" 'sony explodes' in the rear deck. Once the rear speakers are removed you can see the depth of the cavity for replacement. Too far and you get the gas tank. A good intstall shop should be able to see that. Its always a good Idea about your dimensions though to start. Good luck!
