Good day John. I have a question for you. I recently converted my 86 GN to a BBC. Since then, the digital dash hasnt worked. I eliminated the ECM harness. Obviously, I broke a loop by doing this. What do I need to power the dash? Everything else works. Turn signals, security light. I really need the dash for the speedo and fuel gauge. I read something about the (C437) clear connector behind the glovebox. Thanks, Jim
If not, take the cap off the drive, turn the key to run, and pass a screwdriver thru the window slot under the cap. The light should turn off when the screwdriver blocks the slot.
If it does, you may have a worn cam sensor drive.
