I've just finished the Triwi method (wired to both rear wires = short). Works a treat!
Only thing I did different was to use my high beam flasher button (you know the one you flash with your left index finger?).
Disconnected the white and green with black stripe wires from the connecting block behind the dash(these go to the switch), wired them to some figure 8 wire that goes to the abs wires under the seat. Total cost, well nothing except the wire that I already had.
Flick the flasher switch once, and the abs it off until I next restart.
