So a quick hello to you all

Car 3dr Astra h cdti sri 07 plate

Need assistance please Got this car and it's got a few issues, pumkin head unit keeps flashing and then turning off.....
Looks like the reverse camera could be wired into the rear wiring wrongly as the number plate light stays on all the time and also only one of them is working + somebody decided to remove the lift reverse mechanism to put a silly nob on
Need some advice really on a low cost way of getting these issues sorted please

There's not much info to go on but you might want to start by isolating (disconnecting) any aftermarket accessories then work through the wiring/electrical problems one at a time.

If you don't have access to Vauxhall TIS or AutoData it might be worth buying (or borrowing) a Haynes manual for the wiring diagrams.
