Crane ignition box

[Schwab]

Just installed a Crane HI-6N ignition box (blue) and PX92 coil. Truck runs great but I have no tach signal. Crane manual says white wire is tach signal. Crane tech support was no help. Anyone have experience with this? Thanks. Schwab

You might need a tach adapter depending on what tach you are currently running. As with some aftermarket igintions the tach signal is different and not all tach can read it.
