TCU TurboLamik

First of all, Starting to getting everything done, all thanks to the suport of the forum. Big shout out!

Next thing what's left, speedometer.

There is a vss signal out from the lamik. Clear.
My only concern is the type of signal.

My Nissan patrol y60 (gq) normally has a vss on the transfer. But I want to get it working from the 8hp.
Most idealistic is wiring up directly to the cluster.

The patrol has a 2 wired vss with a square wave signal.

Photo attached from. The cluster..
Wirings on the cluster are,

top one is marked 2P, the bottom is IGN. The side ones have a bit of Japenese followed by - and +. These are the speedo signal inputs.

Does someone have any idea if the lamik can send a signal like this, or do I need to convert this signal with a dakota digital interface.

Many thanks!

The TCU signal output is a square wave. However, based on your description of a 2-wire speed sensor, it’s likely a reluctor-type sensor, which typically generates a sine wave. While some 2-wire Hall effect sensors do produce square waves, they’re uncommon in older vehicles.

There are converters available to change a square wave into a sine wave, but before proceeding, you should confirm the sensor’s output. If it’s a 2-wire sensor with a magnet at the tip, it’s most likely a reluctor. You can easily test this type of sensor with a voltmeter—no external power supply needed—to verify its output.

If the sensor is a reed switch you should be in luck but will still need to confirm the voltage range of the sensors output.
