I think that helps a lot. It appears that the one wire is directly from the fuel Gauge (finally got the spelling right
and the other comes from oil unit which is run from the IVR so I am going to assume that that is the power supply that I have been thinking is not working. I guess a simple test of power to that terminal will tell all. Thanks again for the pic. I should know in a week or so. I will be an expert on the Fuel Gauge by then...now on to the steering box and front disk brakes (new post)
