the water temp that i got, only have one wire for the water temp? wich one should i use for this? the pin 96 (pink wire) or pin 97 (blue wire)

What temp gauge did you buy?

it match my tach and voltmeter

That link is not working. Is it their Nitrous brand one?

Also, does it not include a temp sensor of its own? I can't see how a gauage manufacturer would be able to assume that car manufacturers use the same spec temp sensors.

yes is their nitrous brand, and yes it come with a sensor but i dont want to drill a hole on my car for the sensor, but if i can get around it and NOT drill a hole on my car will be better

now for the sensor it only have one cable and you give me two, so i didnt know on wich one to plug it in so i havent test it on any of them yet

now i gues that you r familiar with the gauge that i got, is there a extra hole on the car that i can put the sensor that came with it???


i really want this to work men, thanks for your time

That makes more sense. The more I thought about it, I realized that water temp gauges aren't like tachs, where you can tie them to a standardized signal.

As for where to add your gauges sensor, there really isn't an existing extra hole that I am aware of. I believe that there are plates that can be installed under the thermostat housing that give you a place to install the sensor. I've seen people install them in other cars by drilling and tapping.

I know that others on here have installed them, So, you might want to start a new thread asking where and how people installed their sensors.

that makes sense, ill start a new thread

now let me ask you a question, do you think that if i use one of the line that you told me from the pin 96 (pink) or pin 97 (blue) i think i could try that and see, because i reeeeeeally don't want to drill a hole on my car, and now that i think there must be a line that i can tap into because, on the speedometer there is two light for temp, one light up COOL so when you start the car and the other is the red light that have the signal of hot temp, anyway let me know what you think

thank again for the time

I don't believe that it would work. The single wire sensor is a one wire thermocouple. A two wire device, like what is on the car, is a thermistor. A thermocouple generates voltage relative to change in temperature. A thermistor changes resistance based on temperature. So, the output of the two sensor types is completely different.

As for the lights, they are illuminated by the cluster's microcontroller, based on data from the ECM (who processes the sensor data).
