Exactly, it’s a NTC sensor like I said... the moderator tried to tell me it wasn’t... how about you guys get it right before you start telling me I’m wrong??? It is in fact a NTC sensor... car closed... I am not wrong....
@Phdiesel
And just because I'm in a the mood to drive home how wrong you are because of the way you are addressing some very well known, knowledgeable, and respected members, here is a little real world test to drive the point home. Took my 2 minutes in my garage.
So here is the exact sensor you are talking about (2-wire, ECT temp sensor from a 5.0, Ford part # DY1145, 1984-1995 mustang). I measured this at room temp which is around 55 degrees in my garage.
Then I reversed the polarity of my test leads on my multimeter. Go figure, the exact same reading! (within measurement tolerance of course)
So then, according to your logic, if I would introduce some heat into the sensor and measure, I should get a drastically different reading when I reverse the polarity of my test leads? Right?
Reverse the test leads, and MAJIC! It reads about the same (sensor continued to soak some heat from the heat gun while I was getting the second measurement). But also notice how the resistance value went down, because it got hotter, just like a NTC thermistor should.
Around here, we treat our members with respect. You'll have to learn you can't assume the attitude of someone by the way you interpret their words online, otherwise you're going to have a really hard time on the internet in general. I have never seen any of those guys that responded to you put down anyone (that didn't absolutely deserve it). And after reading what you copied and posted, I can definitely tell you they were trying to help you and you took it the wrong way. Maybe take a step back and take a deep breath next time and try to approach it in a more civil way.

All I said was it’sa to resistor and you guys started telling me I’m doing I’m wrong.. wake up!!! You were wrong... not me.. Jesus..@Phdiesel
Ummmm, what a rant dude. You're not going to get much help around here acting like, but what the heck, let me try to help explain this to you.
BTW, what @Mustang5L5 said is absolutely correct, you can wire it either way. Since you seem to want specifics, it's technically called a NTC thermistor type sensor. A thermistor is a type of resistor. The Mustang ECU sends a 5v reference signal to the sensor and the resistance value through the sensor (depending on temp) causes a voltage to be sent out the other wire that is received by the ECU (just like the paragraph you circled). And you are correct, a NTC thermistor's resistance goes down as the temperature goes up. Also, as you can probably tell by the chart you are referencing, the resistance value is not linear to temperature change.
Here's the kicker, you can wire it either way because it's a thermistor (resistor) and will drop voltage either way. It doesn't care which way you wire it, it's a resistor and electricity can flow either way (no polarity). We're not talking about a diode here.
Look up "does it matter which way I wire a thermistor" and check yourself.
Edit, in fact, here ya go. Just click here and read.

Exactly, it’s a NTC sensor like I said... the moderator tried to tell me it wasn’t... how about you guys get it right before you start telling me I’m wrong??? It is in fact a NTC sensor... car closed... I am not wrong....
It's literally a temperature sensitive resistor, so you're wrong. You can wire it either way and the ecu will get the correct reading, so you're wrong here again.That’s not true... geez... it’s not just a resistor... if you get it backwards the car will think it’s hot when it’s cold and cold when it’s hot and it will adjust fuel accordingly... Please stop wasting peoples time and stop answering questions you know nothing about...
Wrong again, same as above. I even showed you how you were wrong by using real world examples.It’s very clear that it’s a NTC sensor... it says so. And if you’re able to read that chart you sent youd see that it is as well... not arguing but you say it isn’t and the chart and paragraph actually says it is... sorry but, you guys are confused... “as temperature increases resistance decreases” that’s not “just a resistor” Because if you turn it around backwards you don’t get the same reading. Try it for yourself. But you didn’t help me out providing me with the schematic in which my problem is fixed... and for all of you that think I am wrong, go swap the wires on your sensor and come back and tell me your car doesn’t run like....
Doesn't matter your acting like a dbagExactly, it’s a NTC sensor like I said... the moderator tried to tell me it wasn’t... how about you guys get it right before you start telling me I’m wrong??? It is in fact a NTC sensor... car closed... I am not wrong....
you said what?That’s not true... geez... it’s not just a resistor.
and whom knows what?.. Please stop wasting peoples time and stop answering questions you know nothing about...
and this? Am I a 'snowflake'? I'm not even sure what that means.Are you a snowflake that can’t tags direct talk? The first response was a snide one and I don’t special that..
Holy crap dude. You are here 1 day and start flaming people that have been here years and forgot more about these cars than you will ever know. Way to make a first impression.You also know I’m right....LMR agreed with me but they don’t have the pigtail... I came in here wanting to know of anyone else had this sensor I did... not to be told that it wasn’t something that you and I both know it is... LOL... these guys put me down acting like I don’t know what I’m talking about... All I Gotta say each and everyone of you that think I’m wrong take your sensor in your resistance meter and hook up to it and throw it in hot water see what the reading is then turn the leads around and do it again and I swear to God you get a different answer. Case closed you guys need to do your research
Yeah,if the general and 5l5 where not entertaining this-ida already pushed the buttonHoly crap dude. You are here 1 day and start flaming people that have been here years and forgot more about these cars than you will ever know. Way to make a first impression.
You're lucky I am not a mod or I'd ban hammer your azz.
So initial question and first response ...I don’t know how to install this without it being backwards... please help...
Correct answer given in second post ...It can be wired either way and will work the same.
