The PGM-II should be spliced exactly the same way as the MC21, although of course the MC18 M-max box won't have the grey plugs for the G.P.S.
You can actually get a genuine HRC delimter that plugs between the harness and PGM-II like the MC21, but unlike the MC21, it plugs into the standard harness and means you can retain all the road-going equipment. You can often pick the HRC delimiters up on Yahoo! for reasonable money.
The HRC box is trick... embossed with HRC and "Not for highway use", but the wire-splice when done properly is the neatest solution. You won't see the HRC box anyway.
