When I tried to install an mp3 player for my '92 ES300 by myself , I accidentaly cut out a few wires
The next day, the mechanic guy at my local shop coudln't install the mp3 player for me. There was electric going to the mp3 player, but i was unable to turn on the unit. I'm pretty sure this isn't because of my mp3 player since I have tried to install another new cd player and it doesn't work either.
Anyhow, what should I do? It seems the guys at my local shop are clueless when it comes to the wiring scheme--any diagram would be helpful.
P.S. I'm also unable to use the "reset" button next to the odometer reading. What should I do to fix this?
