unexpected cables

[Chimpsta]

Hi

Just had the dash out to replace the blower motor.
When disconnecting all of the cables, I labelled them to make it easier for the refit.
All cables that I labelled have been put back into place and on testing the van, all the faculties (gauges, lights, etc) appear to be working as normal.
However, i have two unmarked cables left over and I don't recall seeing them on the strip out. [photo attached]

One has a plastic connector: 4 slots but only one of those slots has a metal connector inside
The other is a light bulb that comes on when the headlight switch is turned on.

Any ideas what they could be for?

Thanks

Small bulb could be the heater control illumination?

Those are the radio feed connector and the heater control light.
