Schematic I have has an actual light switch shown - I think it probably just loops out at the bar switch (either at connector itself or inside the switch)
You said you have 12V AT the fuse - but is it good on both sides of it?
In & out both Blue/Yellow unfortunately so hard to say which is in & which is out - although pulling the fuse will tell you - the side that remains 'hot' is the one from the KeySwitch - the other side is one that goes to the bar switch connector.
If fuse is definitely good - measure voltage on output side with the fuse withdrawn very slightly so you can access the blade with your test probe - then you need to go on to the bar-switch connector.
I'd be really surprised if not simply the fuse though.
