The latest in the speedometer saga is that the plug I found under the dash is for a gps that was never installed. Superformance sent me one to install. Unfortunately it’s not the unit that matches the installed plug. It’s the unit they are now using and has no plug and different color wires. They provided instructions to install it. However, the wires from the speedo plug change colors at the gps plug. So, the black/white wire from the speedo turns green at the plug and has to be connected to the white at the gps! I found this out with a continuity test. I need to get a battery in the vehicle to do further testing so I can hopefully identify where all the wires emerging from the harness originate. Not a great experience so far.
