[25plusturbo]

hi there i did a retarded thing a hooked battery up backwards

fryed ecu and turbo timer have replaced them and car runs

have no power to windows rev gauge and possibly headunit it had blown fuse though

there is a round black relay under dash by accelerator that clicks every 10 seconds and power drops the fuel pump goes quieter and the dash lights dim and a wierd electric sound comes from near throttle body

when i try put driver window up or down it works for a second then the round relay clicks

i have tryed replacing round relay but still clicks dash is now completely ripped out anybody have any ideas on what it could be
