does anyone know what each of the main 16 wires for the audio system are. Its an 04 x3 non nav/non dsp with factory amp. 8 i know are for the speaker outputs to the factory amp, the rest are not as clear. I am constructing my own wiring harness for an aftermarket stereo while trying to maintain function of the factory amp. I am assuming that the other 2 sets of connections to the factory system are the aux in and steering wheel controls. if I am wrong in this please notify me thanks for the help

| The accessory wire is what turns the radio on and off with the key. Key off = no voltage on said wire. Key in acc or on position = 12 volts on said wire. |

| ok that makes sense. This vehicle had the option of blue tooth and has an sos call button, neither of which i will be using could one of the additional wire be for this? I have also read else where that the factory amp has a ground connected to the radio...black wire. there is a smaller black wire what do you think? or would it be for the speed controlled volume. i will get the other wires colors maybe this will help

| There should be a wire on the harness that turns the amp on. Have you checked the white wire of the factory harness to see if it has a mating wire in the harness you purchased? It should be blue or blue/white. |
