porsche 911/996 light and cluster problem

[mrk1963]

Hi,Got Carrera 4 year 2000.The car was in sea transit so likely battery was jump started. I found that right front headlamp not working at all ,no indicators, no lights and also cluster all backlight not
working as well(can not see current mileage)Remote key does not working too. Checked fuses, they
seems to me all ok,Do you think it could be a faulty light switch , headlight control unit ecu, or bad connection??Please help with advice, thanks
