I BOUGHT A NEW STEROE DECK &WHEN REMOVING MY OLD ONE I BELIEVE THERES A FACTORY AMP ANY ONE HAVE A WIRING DIAGRAM OR ANYTJING//1995 4RUNNER V6 AUTO. POWER EVERYTHING?

 

The best thing to do is go to your local Best Buy or any other store like it get a after market power harness that will plug right into the one that comes off the factory deck/amp. It will make things real easy for you, I got the some truck which did it myself. Plus that harness you buy will have all wire diagram w/it. One thing I will add is run RCA wires while you got everything already out just in case if you might run a AMP if your not already. Those wires should cost around $15 bucks or so ..G-Luck ..
