Just pick up data from circuit my friend, much easier on these. Look at photo and brown wire is at sda, black wire is at scl.

Scrape off to bare metal on the tiny "pass-thru" points and careful solder, dont forget to connect your programmer gnd to tuner case.

Then apply power to radio and try to read. If you get "scl error" all the time then instead do it: apply power to radio, then switch off power to radio. Straight after switch off, bus is more "quiet" for just a few seconds - so you can normally get a read now.

After a few seconds bus goes completely "quiet" so will sometimes take a couple of quick tries to get a read :)
