I could sure use some help!! My oil gauge is going full scale! Sending unit was replaced. Wires to sending unit are fine. But gauge still reads full scale. I have the repair manual but it is not correct for my vehicle. For instance on my cluster the flat connector has 8 terminals. The manual data only shows 4! Also the picture it shows for the 1986 does not match mine! My VIN # of 1QJCNJ1508GT987285 Indicates it is '86. Thus why are the manuals that I have purchased of no help...
