Thanks for reply!
Fuse 27, is that one of them that sits underneat the dash/speedometer nearby the footwell? From what I can see there is some red/blue wires Attached to relay/fuses there but I can not see if they are numbered (like 26,27 etc)..
I have tacho, temp sender, fuel pump and ignition live at the multiplug now, only missing 12V live feed now to sort this. Was hoping to get this feed from inside the car where it was supposed to be from Stock/factory..
