I have found the wiring diagrams for adding this. Bought the connectors now I need to know how they are numbered. Nobody shows that, meaning that they call for the audio out neg and pos being in slot 1 and 2 on the headunit. Which ones are 1 and 2? Thanks.

Would be great if somebody could take their radio out and shoot me a pic. I just need to know where the wires go in the connector or how its numbered.
