Hi sewin. If you can drop the dash there is a bomb tail (group of connected wires) in main loom distributing the run position power out of ignition switch. If you can trace this main loom to the grometted hole where it passes forward through bulkhead into engine bay then work back 230mm on the dash side you should find this bomb tail taped back into loom. There should be nine white/orange wires which you could add to. Note at this point they are only fused by a common 30 amp ignition switch fuse though. Alternatively you could tap into the green wires feeding demister, heater fan or wiper switches which are fused individually via main fuse box.
