Thanks JT - Antenna makes sense I guess as it's a two way toggle and getting power from splicing in to the brown cable and had its own seperate inline fuse...
I'll see how I can creatively deal with either hiding a hole or finding something to do with the switch - ignition shut off makes some sense as a starting point.
