Instrument cluster swapout help

[JudgeM]

Hi again.

Yes I am looking for the same color as my old meter. I dont really like the color, but I have OCD and I want everything to match and I wanna try to keep the car looking original.

I had a look at my radiator, I coudnt seem to find anything resembling the temp sensor. Although I did see a black wire and a white wire going near the radiator, I couldnt trace where they lead to.
Could you please tell me where on the AC ECU i can see ? I had a look and I dont think I was looking at he AC ecu.

I did a preliminary road test with the new meter, and speed units can be changed by holding down trip button like u said, but the milage stays in miles. No way to change that I guess becoz the VFD does not have any unlit text saying km/h . Also, the fuel consumption is in mpg, i do see in the VFD a km/l . I managed to use Techstream to change it to km/l
I love the digital speed, the bar graph RPM will take time to get used to, it feels laggy compared to the analog.

I have a more serious problem though:

1) The indicator lights are all wrong. I get the hi beam indicator permanently on, the turn signals are flashing things like the battery light etc. Strange but it seems as though the JDM and EUDM have different wiring. CTScott, do you have a wiring diagram for these so I can confirm and reroute wires? I could only find USDM wiring diagram.

2) I have a permanent beeping and a symbol (cog with ! mark) even when the car is off and doors locked. Does this have something to do with the person I bought this from saying that it will have to be "coded" to work in your car. Do you know what this means ? Can I do this with Techstream ?

I've attached pics for reference
I appreciate the help.

Here is where the ambient temperature sensor is mounted behind the bumper. It is visible through the lower grill.

Here is where the AC ECU is located on left hand drive Yaris:

I put together a conversion chart for US to European clusters a while back and just updated it with a third section for the Japanese Vitz. The turn signals are wired in the same place on all three, so you should double check your extension wiring.
