Yet another question about aftermarket water temp sender
So I have searched..... and read a million threads about it.... but all the pictures and comments seem to be more 3rd gen specific.
I have an idea I am tossing around - and I want everyones opinion...
I found this pic on this site from someone that tapped the TB coolant line on his 3rd gen.
I was thinking about doing the same, with a different line.
There is a hose in the 2nd gen FC that goes from the engine block to the heater core in the firewall. This should work just as well right?
Please give me your feedback. I am going to try this in the morning if everyone agrees.

I wouldn't tap that spot because I'm pretty sure that coolant only flows through that line when the heater is switched on and calling for heat. You're in FL so I'm doubting you use the heat very much, certainly not in the summertime. I would think that putting the sensor in that spot, out of normal coolant flow, would bring you a 'dead' reading - it would be like tapping the sensor into the CAS and saying, 'Well, I'll know the engine temperature because as the engine warms up, so will the CAS.'
I would go with a 'live' spot where the coolant is flowing all or at least most of the time. The water pump housing is probably the most-popular spot. It's what I chose.

BUT.... I really like your idea... I am actually going to do it exactly the way you have in your pics.
Thanks!

The water valve is part number FB01-61-A40, controlled by the temp actuator, part number FB01-61-A60A.
Found on the drivers side of the car, just above the transmission tunnel.
No coolant flows through the heater core when the temp indicator is set to cold.

Makes no difference where I am from. I could ask if all Americans are this ignorant, but I know its not the case.
I don't put up with people posting misinformation just for the sake of increasing their post count. It is extremely irritating to watch someone tell someone how to do something completley false. I would hope you would rip on me if I went and told someone to wire their house with 20 gauge speaker wire.

You can also tap the back of the water pump housing, so that the sensor's not right next to the belts and pullies. There's a nice boss there that you can drill out and tap next to the stock sensor. It's not that hard to do and I for one never regret doing things the right way.

If you had a house and you were deciding where to put the thermostat, would you put it in a fairly central location or would you put it at the end of a long hallway that had no vents nor other sources of air circulation? Which location would have the more useful, more realistic reading?

Copied and pasted from the FAQ:
Where do I install the sensor for my aftermarket temperature gauge?
There has been lots of discussion about where to mount water temp sensors/senders. The best location is on the water pump housing near the stock ECT (Engine Coolant Temperature) sensor. Drill and tap according to the threads on your sensor (usually 1/8" NPT). It is important this this sensor be installed before the thermostat. See the following topics for more information:
