Injection Pump RPM sensor

I swaped in a 1KZ-T in a BJ74. Now the rpm issue arose since the old system was engine-rpm from tranny. 1KZ-T has the rpm sensor in its injection pump. Can anyone tell me what kind of output does this sensor in IP produce (pulse/voltage )? I am working on a project and I need some...

Thanks i read that but in the end i did not understand if you need to change something in the instruments panels to make it work.
The ohms are the same in the post, but it does 6v could it be some condenser burn inside off the dash?

I think you need the correct 1KZ T tachometer to use the signal from the 1KZ injection pump sensor.

I bought the instruments pannel of a lj70 thinking that was from a kzt but it did not work also.
I try to put the tacho of the VM in the LJ pannel and its moves a litle the needle go up a bit with the engine on high revs. does the same in the VM pannel. but the tacho of the LJ do not move on any of the pannels nothing.
Problably os burn?
Should the tacho of the LJ work with the kzt? Is not the way of reading rpm the same um the 2lt engines of the LJ?

leave it hooked up for a while?
my standard tacho doesnt start working till about 15mins of driving,dont know why this is,some kind of fault,been like this since I have owned it, fine once warmed up and will work straight away from shutting it down to restarting the motor.
