totally different.
afaik the tacho feed comes from ECU not directly from the pump.
you will need to change the tach itself or fit a converter.

I used this Jaycar kit to change the signal from my manual pump to tacho
When I got rid of the electronic fuel pump in my 1KZTE....
Note: manual pump is a hybrid 2LT one so should have the same tacho pickup on it...

Its been discontinued.
https://www.jaycar.co.nz/speedo-correct ... t/p/KC5435The replacement kit may not work.
As the previous kit could be adjusted to different input signals and then pass them thru as new signals.
Best fix is to get a tacho from a 2LT and swap them over in your instrument cluster.
Did that for mine as the Jaycar kit was a bit jumpy...
