Toyota 20 pin AUX connector. Which wire is Which?

[yellowmitch]

Thank you VERY much!!

If I connect the orange and green together on a 3.5mm line socket and connect the purple to left and the blue to right, will it then just work?

Where can I get the 20 pin connector, or should I just cut it off and fit something easily available?

A resistor is needed with the switch line. I believe it is 2.2K. There is a thread on here somewhere where I posted the correct value.

I would just snip the connector and wire it directly to your input jack.

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.
