I need the color codes for the factory radio wires, to an aftermarket radio, and speakers. Connection straight to the factory and bypassing the amp.

Hello,

Here are the wiring diagrams for the radio and speaker, I noticed there is a telephone ECU inline for the left door speaker which will need to be by passed as well. Check out the images (below). Let us know if you need anything else.
