Running into a wall on this now. I have a Dakota Digital signal converter installed on the M60 swap. I cannot get any of the tachs I have to register. The cluster that came with the car worked when I got it, but then it sat for 2 years. I read the SI board batteries can go bad so I took it apart. Batteries badly corrided, broke a connector trying to get them undone. So I put the "new" cluster in that I had bought that had a 7000 rpm tach rather than the eta tach. That one wouldn't work. So I took it apart. Same issue, corroded batteries. So I got ahold of Bavarian Restoration to get them rebuilt into one. They said don't waste your money, get a new style cluster. So I did. Just installed it, still no tach. This is out of a M42 car, so I completely took the Dakota Digital unit out of the equation and just hooked the tach signal off the ECM to the wire going to the cluster, figuring it will just read double. NOTHING. I have checked continuity, I have verified the pins, I have checked resistance. Nothing is out of line. The Dakota Digital unit flashes that it is detecting a tach signal from the ECM. So WTF is wrong here? I don't have any wires hooked up to the "Green" connector on the cluster, because it was only 1 wire, and I can't figure out which of the multitude of pins it should go on, or which wire it even was for that matter.
Any advice? I was really thinking the Dakota unit was junk, until hooking it direct to the signal from the ECM did nothing. Getting beyond frustrated with this situation.
