G-21 tower wiring diagram

[shag]

Does anyone have a G21 (2015) tower wiring diagram? I mounted this on my 2008 SAN 230, and it has speaker wires on port side, and what I assume to be the nav light wiring on the starboard, but there are four wires and the tags are not really readable... I believe I can make out 'ground' on one of them.. Wondering if the speaker lights are in these as well, and how - what to splice them to.. Don't really want them on all the time with the interior lights.
Thanks.
