I don't have any pictures off hand. If you Google image "90-91 suburban electronic speedometer"......you can get an idea of what they look like. Main thing is that it has the circuit board on the back (like on the first page of this thread) rather than the cable connection. Also, I'm far from an expert.....but it seems that the electronic speedometer has the word "Quartz" on the face and resolution to the nearest mph.....rather than in 5mph increments.Happen to have pictures to see what it is supposed to look at?
