Taking a fresh attempt now using the diagram.
Fuse 39 5a is yellow, bottom right in diagram 3.
On that same block are the following:
---
Fuse 33 - Deactviator Switch & Brake Pedal Positioning Switch
Fuse 27 - Radio
Fuse 21 - Instrument Cluster, Powertrain Control Module
Fuse 15 - Left Front Lumbar Adjust Switch
Fuse 9 - Front Subwoofer Amplifier and Rear Subwoofer Amplifier
It says 'from splice s260 on diagram 1 of 3' under the hood:
Fuse 13 - Electronic Flasher Module
Fuse 6 - 40A
It says 'To fuse 27 Diagram 3 of 3'
Fuse 27 - Radio

I am going to remove Fuses 13, 33, 27, 21, 15, 9 and re-test after 45 mins.
I don't have aligator clips, i hope i'm not waking it up by when using the multi..
Hope this approach is good
