Volvo480 project - working on the lights and electrical system, plus refitting the interior finally

Making more progress on my project Volvo 480 from 1997. This time I'm repairing a light connector that has melted in the popup headlights, checking all the bulbs and resolving why one of the rear numberplate lights stopped working.
I also start the car up to check it's starting and we have no fuel leaks after all the fuel filter and pipework I've replaced.
The car is slowly getting ready to go for an MOT now it's electrical systems and lights are all back in place.

Seems yo have a couple of position rear lights burned. they are double bulbs, each side. The light on the dashboard usually lights off when depressing the brake.

My Volvo drives me crazy, I got blinkers, got hazard, got "high beam" but only if I am holding the stick, but I don't have any other light. Does pop up no light, nothing. I hope it's not my CEM, costs nearly 400 euro.
