man i know this is an old thread, but dang now this is some good class A work! I just saw that our altima made the ATC today and started to look into it and hope someday to make this a reality.

I had to put off the completion of this project until next year since it has started to get cold in my area and my free time has been greatly reduced. Besides, I'm a whimp for working in the cold weather.
But I'll hang around here for anyone needing help with this type of project. Glad to see that this thread is proving useful in one sense or another to many of you.
that's some good work.. i just bought a unit but was not sure how to complete the project till now. perhaps this winter i can get on it and get it done. sweeeet.

You guys thought I'd leave this thread hanging...fools...well spring is here and I'm back to add some more goodies to my projects. This time we'll get the ambient temperature sensor installed for the ATC conversion.
The first thing you need to do is to remove the front grille. We need to add the ambient temperature sensor and it's bracket to the bottom side of the center support bracket. Shown here in white,
Man, look at how much rust damage all those years of driving can do. I'll have to figure something out for that sometime in the future.
You will then need to install the ambient sensor on it's support bracket. I had to drill the bottom hole of the bracket a little wider because the sensor wouldn't snap in properly.
You can now proceed to install this ambient sensor to the correct location defined for it. You will need a 10mm bolt to hold it all down.
Next you will have to get the sensor's plug and run the wires to the wiring (orange/black and black/yellow) that you left hanging at the foot of the driver side. I will need to do that later and show you guys how I ran the wires.
That nearly completes the ambient sensor side of the project.
Still remaining on this project are; to solder some wires for the illumination, thermal transmitter, and a couple others that are sitting behind the AC control panel. Finally, we will need to run full diagnostics, calibrate, and tune the entire system.
We are on the final stretch here and everything it finally coming together. Thank God.
would a calibrate and tune be necesary even when its a stock systemin a gle? also what triggers the ac to go on? is it just when u are at 65?

The idea for calibration and tuning is to make sure that the sensors are reporting correctly and the system is outputing the correct air temperature through the vents as described in the field service manual. It never gets done by anyone so you can imagine many of our systems are sub-par. I won't write about this until the very end of this writeup.
The AC comes on based on a signal from A/C switch, the Thermal Control Amplifier, and the A/C Triple Pressure Switch.
ok jserrano/i gather some of the needed parts for this today,sunload,front temp sensor,which means i need the aspirator,thingy behind the glove box,thingy behind the radio and the hose to the aspirator, what im i missing beside the plugs to them,can i buy wire to wire this in or do i need to it like you did?
I like to try and keep wiring as close to OEM as possible. The best option would be to locate a harness which has ATC. The next option would be to find a non-ATC harness and use whichever male/female connections you can find that will serve the purpose, electrically. The last option would be to hardwire (solder) the electrical wiring in place. But with this last option you don't have interconnections and won't be able to quick disconnect anything.
the only one i can get ahold of is in the junkyard,but if you would like to buy the parts that i bought today then you can,i have a sun sensor and the outside temp sensor
