My modification worked! I have a 1998 Boxster with cruise control. I first tried the poor man's version, and that worked perfectly. I used two foot well switches to get all 4 functions up, down, reset and gong. Hitting the switches while driving takes too much attention, and makes using the functionality is a bit annoying. I'm just about to install the 4 stock part on the steering wheel. Couple of observations.
1. the instructions are perfect
2. the VW wiring parts avoided any problems with pins etc. They just fit
3. Various leds and status lights did not work after putting the gauges back on the first time. It was a simple careless mistake. The black connector behind the gauge was not completely pressed in. Seems that when Porsche had replaced a gauge bulb in the dash, they broke or removed the connector cap that "locks" the black connector to the male connector behind the gauges. I didn't get the connectors snapped to together properly
4. If you have the temperature showing, then your OBC is on!

Great! Thanks for the additional info / feedback. I'm going to copy this over to the forums so that others can see it as well.
