What year and engine? The wires between the servo and cruise module first go through C500 which is the large block connector by the battery. From there they pass through the firewall and go through C245 which is located on the left side of the center console down by the gas pedal area. The cruise module is also in that area. I can post the diagram from the Factory service manual if you can tell me Year and Engine.
