Hello guys,

I own a Honda Prelude BB3 from 1992. I have an issue that I cannot figure it out and I am writing to you with the hope that maybe someone can help me.
The issue is: my whippers are going without stopping. They start by themselves, I do nothing. There are 3 gears for the whippers and it starts in the 2nd, but if I command to go into the 3rd gear, it goes, but never stops.
I obviously think that it is an electrical issue. BTW: I changed the "button" commander and the issue it's still there.
I contacted electricians, but they are telling me that because the car is so old, they cannot find the issue, they need the electrical sketch.
Does anyone here knows/encountered this issue or has the electrical sketch of the car?
