Hi Garrobo. If you have a digital copy of the service manual, please upload it.
I scanned page 27, and uploaded it (page 27 - Fig 13 - drive wire cable routing). The quality isn't great, but the scan looks pretty close to the actual page that I have. As I noted previously, Sakura USA did not have a digital or even a premium copy - just photocopies of photocopies.
I hope that you will find it usable.
