    /forums/images/icons/confused.gif I have a transfer case from a 90 K5, and do not know if it takes a manual or electronic speedo sender. The case will be put into a 1991 K5, so it will need to have the electronic one. I have heard it both ways, so I need a way to check. Thanks for any input on this.

    I have a '90 case that has the electronic type, are you asking how to visually tell the difference? on the tailshaft extension, where the rear drive shaft slides in, an electronic speed sensor will have a two wire plug for the sensor wire to plug into, the sensor will be threaded into the extension housing, a manual speedo drive will have a threaded sleeve with a square hole in the center for the speedo cable to screw onto at the same place in the extension housing
