Converting normal aircon to climate control Options

[S8S8]

I know there's a great thread started by Cavegod on fitting climate control to a non-aircon Celica, but I'm looking to convert a normal aircon Celica to climate control.

Has anyone done this before? Cavegod's thread should be of great assistance, but I'm guessing my conversion should be a little more straightforward since I already have aircon.

I have a JDM SS-II front cut, so I know I have all the necessary parts, but I also know that it's definitely not just plug and play! Here's a few observations so far:

• The two aircon compressors appear to be exactly the same, right down to the same three-pin plug.
• Both dash units use the same plug (see first picture below) however the JDM harness has a lot more wires going into the plug. It seems my standard harness does not have the additional wires needed to run the climate control

Here's a pic of the back of the two dash units, with the standard aircon unit on top and the climate control unit below. The middle plug on the standard unit is just for the fan speed control dial, which is not used on the climate control unit.



And here's the front for anyone who is unsure of the difference:



I'd love to hear from anyone who has done this swap or knows anything about it.

Thanks.

The JDM one has temperature sensors throughout the car, I'm not sure how many or where but i'm fairly sure the thing on the panel under the steering wheel that looks like a mini grill and has a rubber tube plumbed into it is one of the sensors (unless your car has this too)

I suggest you pull out the climate control loom out of the clip and trace it back to whereever it forks out. just destroy the dash if you need to, it's pretty much junk to you anyways, just save the bits that are better than yours

if the climate control harness joins up with a main body harness just splice it up and see where it goes
