Hi to all,
I need your experties. I successfully installed an OEM 6 CD Stereo model 86120-AE060 taken from a 2007 Sienna relacing my single CD stock stereo in my 2004 Sienna. Everything went great and all works.
Now, I was thinking about buying the AUX module which comes in 2006+ models (Dealer Part Number 86190-AE010) and attaching it to my new 2007 CD changer. I expect this should work since both of these modules suppose to coexist. What do you guys think, will it work? Has anyone else done this? Am I missing something? I understand since my 2004 did not have AUX natively I will have to buy wires that will connect into my head unit. Do you know where can I buy them?
Please help me. It will be greatly appreciated it.
Best regards,
Here are the parts pictures

UPDATE:
I was able to fabricate the existing Engine Immobilizer and install the AUX plug using SeanY's directions. Engine immobilizer still works at its current place. I did not move it as Sean did. I hate soldering. Anyway, now only 2 things I need to know.
1. Where can I buy the cable that will connect my AUX port on Radio to AUX Module? Part number will be very helpful.
2. Which port is the AUX on my radio? Please refer to my radio in my previous post.

Thank you guys in advance.
Regards,

Anyone??? Where are the fans?
