Was the electric speedometer only used on the 90-91 models ???? I know it has nothing to do with the fuel injection- so to speak anyway- because the GM trucks have been injecte since 1987 and I KNOW that the 87 and 88's's did not use this type of speedo.
What was the real reason for using it. thanx ,crossy
