Toyota 20 pin AUX connector. Which wire is Which?

Ok. Thats great. I take it that the resistor flow must travel towwrds the radio? Am I otherwise correct in how to wire this? Does the proper toyota socket have the resistor built in? I am sorry for asking so many questions but I want to be sure I do it right first time.

No problem. The resistor is connected to the switch contact of the 1/8" phone jack on the OEM one, so when you insert a cable the contacts close providing the radio with a 2.2K ohm resistance to ground on the AUXI pin.

So, you would solder the resistor between the green and orange wires.

If you are using an OEM Aux jack, then you don't need the resistor, but if you are making your own then you will.
