Hi -- do you all know if a tach from a 94 Terrano (UK model, TD27 Turbo, auto trans) could be transplanted into the cluster for a 94 Navara TD27 Nonturbo, manual trans? Visually they look the same, though I am unable to confirm precise part numbers.

I have the source and target pictured below. I am thinking about buying the "source" from an overseas supplier to replace the dead tach in my cluster.

Thanks for any advice/wisdom!

no idea with nissan, but a lot of terrano's where ecu controlled and ecu controlled pumps can have different rpm output signals from the injection pump.
i have a toyota that had issue, i had to get a gauged that matched the injection pump (tho there is signal converters around).

I ended up swapping the tach from a TD27 turbo UK Pathfinder into my TD27 nonturbo Pickup (JDM). The part numbers were exactly the same - K26061 73P03 -- but unfortunately the new tach is still not registering. It's completely dead when the truck is running.

Do I need to check the tach wire now with a multimeter, at the back of the gauge cluster? For constant voltage, and then rev the engine to see the voltage rise? Is that how it works? I have a shop manual so I can probably figure which wire.. but it seems really difficult/intricate to do that.

Thanks

not really, tho you may get voltage readings. the sender sends pulses. i would check the feed off the injection pump first.
