I have Sandel 3308 too. Would like to interface it with the AP.
After reading your post, called Sandel today and their phone is disconnected. So it's looking like not going to get any further support from them.

their website is still active and the installation manuals can be downloaded from there.

Appreciate patrolpilot's help!
I do have the install manual for SN3308 which I have studied for some time. But Patrolpilot mentions a "King/Bendix autopilot adapter (which required a modification)" and this came from Sandel. So sounds like important stuff. An autopilot adapter is not in the installation drawings from Sandel.
