I recently bought a sony stereo, to replace the stock benz one. I pulled out the stock stereo, and realized this was going to be harder then I thought. I striped some of the wires, and started the tedious task of touch each wire to the next to get sound. Anyone have a guide on which wire is what? The color of each wire doesn't make any sense to me. I already found the power (red from benz, yellow and red from aftermarket) and the ground (black both ways) Thanks for the help.
