Hi Spook,

I'm gonna mark this thread with the pulldown for 1993 year. Please change it if that is not the correct topic.

The output which operates the fuel computer idle control and cruise control is combined in the speedometer at pin 2 on the gauge connector. I am aware of this only because you provided the example unit for me to repair and document.

Logic would have it, if the fuel computer was not setting a 311 DTC, a cruise fault would not originate in the gauge, but if related to that signal being missing, would lie in some external wiring on or around the instrument cluster.

I vaguely recall someone making a detailed post here on BB showing some loose pin or broken trace they repaired to get this signal beyond the gauge itself and to the cruise computer. A mechanical problem with an electrical wire. I'd have no knowledge of that myself, having no 900 model Volvos to worry about.

To answer your query, I pulled up the page http://cleanflametrap.com/speedo7.html which toward the middle begins a series of pictures of the repair of the unit you sent me some time ago. Scroll to "1993 Speedometer."

I hope this helps you, and I always enjoy hearing your on-line civility expressed on this forum.
