The best way I've found to do it is to use a relay, as posted above. There should be a 2-pin metri-pac connector on your harness right where the terminator is/ATU harness plugs in, or if you've got a full GSReady harness, a 2-pin weatherpac by the ISO connector. Tap into the white wire - grounding/opening that wire turns the mapping on/off. You can set it up either way in the monitor, as NC or NO.
