NB Coolant Temp OEM Gauge Sensor
The tiny little water sensor in the back exhaust side of the head that feeds my gauge cluster broke off. I've found several similar on ebay/amazon/autoparts stores, but can't find anything that claims to fit a NB Miata.
Is it just some generic part that fits tons of cars and anything will work? I found one that claimed to fit 90-97 Miatas and figured there's a decent chance that works. Anybody know where you can buy one or have one they want to sell?

Mine definitely has 2 separate sensors.
Looks like this:
The little prong thing fell off and now my gauge cluster reads full cold, but megasquirt still reads an accurate CLT temp from the sensor you posted.

I needed one as well when mine was lost in my swap on my NB. Bought a new one for 20 bucks at local parts store.

I assume when I swapped it back into an NB I just kept the Ignition/Fuel harness so I could reuse my injector clips and COPs. Apparently the NA and NB harnesses are interchangable so my dumbass must be using NA temp sensors on my NB, that apparently work fine.
So thanks for helping figure that out. No wonder I couldn't find the part that doesn't exist, I guess I'll just buy the NA sensor and call it a day.
