Hi all,
I got a 06 Scion heatunit and try to figure out how to make the aux function works. I have searched on this forum and the aux function is still a mystery for who install a 06 HU on a 05 scion.

Can someone please post some pictures of the stereo (aux) adapter? I want to know how that 4 wires connect to the adapter. Pictures showing the internal construction of the adapte will help a lot because I want to make one.

Thanks.
