So does anyone know what the values coming from the Brown/Blue and Brown/Black wires coming from the computer should be? I know the solid Brown is ground.
I have checked the values and found the following. The outside terminals each read battery voltage while the center reads 22 ohms. Ordinarily I would just run an auxilliary ground when I find a high resistance like this but the high voltage at the end terminals has me wondering if there is an error in the diagram? I know if the wrong wire from the computer is grounded it can ruin the ECU. Any suggestions? I am considering checking the wire at the ECU connector to check the continuity but it is just way too cold out there.
