Hi, welcome to Just Answer

Ok I can not get you the wire colors for the speedo. What I show from my diagrams and stuff is that it is wired from the VSS variable speed sensor to the guage and not through the PCM. I would follow the variable speed sensor. I am not sure but I believe it is at the back of then transimission or the rear axle. Either way these wires should be the same color as the speedo. I included the basic info for installing the speedo and the cluster.

REMOVAL & INSTALLATION

See Figure 1

  1. Remove the instrument cluster, then the bezel.

  2. Unscrew the instrument from the cluster.

  3. Carefully remove the instrument from the front of the cluster.

To install:

  1. Install the speedometer.

  2. Install the instrument cluster.
