coolant temp sensor question

[ducky]

I'm still trying to figure out how to turn my coolant light off after terminating the stock reservoir and connector..

Ok guys after doing the 3 wire camaro sensor and pigtail, my guage still don't work.
I now have the adapter and got a new 95 sender but it is two wire. Is this correct? I know just one green wire goes ti the guage but what wire on the sender is it? I don't have my stock sensors to plugs anymore.

Not sure about the 95 but my 92 was a single green wire sensor was only one wire. The 3 wire camaro sensor worked perfect for me. Did you wire it correctly? Check out this thread. http://www.ls1truck.com/forums/lsx-t...or-wiring.html

Yes I had it wired just like that. I have a extra wire in my psi harness that is for the 3wire sensor. Maybe I should've ram my own wire from plug to green guage wire.

Anyway I found in pics of my old motor was the temp sensor by the upper water neck had a 2 wire plug with one yellow and one black wire. I haven't traced it further just yet.

I ended by drill the water pump and tap it with a 3/8 NPT.

i found thsee pics from what i took a while ago. this is the "sensor" which goes to the pcm and yes your right that it is next to the water neck and has a yellow and a black wire. this IS NOT used for your gauges. i may be misunderstanding what your asking but you shouldnt need this sensor on your new motor as it should already have one. you will need the "sender" which has a single dark green wire going to the connector and the sender itself only has one pin on it even though it looks like its made for a two pin. the sender is what goes to the gauge and it is located on block on the driver side of your old 350. you will need to retain that sensor or buy a replacement if yours isnt working/lost it, utilizing a metric to american adapter. 12mm x 1.5 to 3/8 NPT. idk how your psi harness is wired but i reworked my own and i traced the dk green from the gauge to confirm i had the correct wire. hope thats what you were asking...

btw, i dont have any pics of my SENDER or connector for it off hand otherwise i would post it so you know what you should be looking for. sorry. maybe somone else has some.

Yes I need to install the factory sender for the gauge in the pass side head. I got the metric to 3/8 adapter. I just can't seen to find a sender or connector. This Should be at autozone or orilleys?

I had a link that used to work but anyway you can take a coolant sending unit and grind it down and rethread to to the metric size. Wasn't all the difficult to do and no adapter involved

I found the 1 wire sender at napa #ts4019. And with that I was able to find the 1 green wire connector. I had cut it off and set it aside.smh. Thx guys
