S13 REdtop coolant temp sensor.

[95zilvia]

So I have isolated my idling/running rich/stuttering/bogging problem to my coolant temp sensor. But help me confirm a couple of things.

It is the sensor for the ECU, not the gauge cluster correct? Actually, I am sure of this because my coolant temp gauge on my cluster functions.

I checked the FAQ for SRs, it says I can use a temp sensor out of a ..
Engine Coolant Temp. Sensor:
'91-94 B13 Sentra SE-R
? Is that correct? This is the one I need right?

Water Temperature Sensor
Sentra - Goes according to what year your SR is.
Differences are in 91-94 and 95-98
Sentra: 91-94 have a rectangleish plug while 95-98 have a slightly slimmer, more box looking plug.
Redtop and midyear S13 blacktops use a z32 sensor. I believe you should go by year as well if buying a Z32 sensor.
Late S13 blacktops use the Sentra sensor.
KA water temp sensor doesn't work, or at least it didn't for me. (S13 98 Blacktop)

or is this right?

All I know is, Phase2 sells the sensor for $29.99 plus $8 shipping, while I can get it local thru my nissan guy.

So.... z32 sensor? sentra sensor?
