Dido !
Mine now works on and off when it feels like it. It seems to stop working after long trips(1 hour+). I relocated it to behind the battery tray and that seemed to help a little in reliablity. I also think that when I tightened the pins on the connector that helped too.
Let me/us know if you find a fix!
I have a question(for everyone): was the 1995 IMRCs reliable with the vacume secondaries?
