Toyota 20 pin AUX connector. Which wire is Which?

[yellowmitch]

Hi there,

I have a Daihatsu Sirion car (same underpinnings as yaris, sold as toyota passo)

anyway, I am looking to connect up to the AUX connector on top of the radio.

It is a toyota 20 pin connector

There are 4 wires on top of the unit on a 20 pin toyota type AMP connector. The colours are purple, orang, blue and green/grey(not sure)

I take them to be left, right, common and ground detection

I have sent a link to some pictures - https://picasaweb.google.com/lh/sred...-EF&feat=email

I just need to know which wire is which. I assume then that I connect the common and ground together on a 3.5mm jack and then the left and right separate

All help much appreciated

Alan
