Bj70 tach

Hi will a tach from a 12v bj70 work with the signal from a hzj75 injection pump?

I doubt it, the tach sensor on the BJ70 is a hall effect sensor reading the teeth on the flywheel. So the tach would be getting 110(?) pulses per revolution.

The 2H/12H-T uses the same sensor as the 3B, so if he gets any response it may be helpful. 1HZ tachometer signal conversion? - https://forum.ih8mud.com/threads/1hz-tachometer-signal-conversion.1245354/
