Suggest you check for most bus modules by doing a vin check and looking
at the options listed.

the above is good for pinouts and chasing fuse
positions down.

Year model and options would be needed for an
intelligent response.

Most of the aftermarket harness don't let the most bus shine through. No aftermarket head unit has a most bus connection so it doesn't matter anyway.
(well at least last time I checked)
Thanks again, I was installing a Pioneer SPH-DA230, everything was working fine until I unplugged it.

Unfortunalty I can find any free VIN finders online so i will have to dig out my V5 to check.

With regards to the most bus light, this was glowing before, I plugged it in, when i removed it again it's wasn't shining.

Hence my thought that it may be a blown fuse.
