Audio signal and power wiring

I know I've posted similar in the past asking about power feed (and had help from AndrewG and IanL) but this is a bit of both so started a new topic. In an attempt to nail which fuses and wiring should be working in the convertible, I checked through the EL section in the manual. The relevant section from the 1996 manual is EL-177 to EL-186. In particular I'm looking at the wiring diags on:

EL-178 EL-AUDIO_01 Except Bose System
EL-179 EL-AUDIO-02 Bose System
EL-180 EL-AUDIO-03
EL-181 EL-AUDIO-04

It's very confusing. Look at the speaker connections. None on 01, Doors for the Bose on 02, Rears on 03 and Doors on 04.

My guess is that
01 is common to 4-speaker set-ups (i.e. LWB and SBW)
02 says Bose but I think this is for the connectors (it's the only diag other than 04 which shows Door speakers).
03 is common for the Rear speakers.
Also, check how they show the Radio and Cassette Player with wavy lines indicating continue on next page. I think.
04 is for convertibles - it's the only one which shows just Door speakers and has a complete non-wavy Radio and Cassette Player. Also repeats some connections on 01.

What do you reckon? IanL or AndrewG or other convertible / audio gurus?

Thanks
