Few electrical niggles

[hunker7]

Hello fellow owners, have few electrical issues on my newly acquired D2.

1. Trip computer won't register that boot is shut? Where is the sensor for that, can't see one separate, is it part of the latch?

2. Lights won't come on in the boot, no +12v to the bulb holder? Could be related to above?

3. When I unlock the car only front interior lights come on? Rear comes on when I turn front on, but they won't come on with the rear switch? Makes sense?

4. Now it's bit chilly outside, trip computer screen is very dark? Once car warms up it's nice and bright?

TIA
