Help for sony XR-3324 - I want to add Auxiliary Input

[nominds]

Hi all

I have a old Sony XR-3324 Cassette player (a car stereo) working perfectly. I want to add auxiliary input to this so that i can play music from external portable devices. I tried finding the service manual for pinout information, but couldnt get any.
I request you , if anyone has a service manual (not owners manual) for Sony-XR-3324. OR Pinout information of this model.

I Could read on the IC as "SONY 270-07 4E1" which is on the back with heatsink.

Thank you all

thank you, but the link doesn't work.
And also that site needs registration, and registrations are available only through invitations.

I didn't have to register. Email me for the manual.
