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
