A31 Digital Climate Control

[Nic_A31]

^^ tested mine and it still works all good. Plugged back into Cefiro, turned it on, off, took it out and tested again, same deal. Still works.

i was thinking about this myself but im a bit confused,....on a s13 when you turn up the heat for example or change the heats direction from say the window to the vents with the digital unit isnt all this done automaticaly in a s13 with motors?wear as in the cefiro its done manualy by hand.did you have to put in motors ect?or am i totaly wrong and confused hear?

[Dan_J]

i think your both wrong and confused, what is being said is once you pulg in a digital control on a non modified wiring plug you will blow a circuit effectively making the unit work as it did before( blow air etc ) except for when you modify the wiring to make it work something will be wrong with the unit.

[200sxs13]

from what i can see when you plug the unit into and unmodified loom it will do damage?anyway thats not what i was on abut my post was in refrence to the original poster off this tread and the fitting off this item correctly as im wanting to do this myself,in an s13 usuing the digital unit,isnt air directing,air tempetaure controlled automaticaly by motors opening and closeing vents behind the dash?in a cefiro isnt done manualy?i know some off the functions are done off a switch but like the hot/cold is turned up and down manualy by a leaver is it not?

[Nic_A31]

No.

Cefiro air con looks like an analog piece of shit, but there is no levers / cables etc.

Cefiro stock air con is actually climate control.

Take it out of the dash and have a look.

And dunno wtf you smokers are on about Tested my unit twice against 2 different cars - works fine, still.

i'm a lil bit confued about that,...you wrote it works at you, you just plugged the stock ceffy plugs in the s13 digital control and it worked or what?(if i understood it right^^)

[Nic_A31]

I plugged it in...it didn't work but its not dead either.

[o0o]

hmm i wanna try if i could get it work...atm i can't find a s13 control, will one from a r32 work or does it have to be from a s13?

answers lie within

[o0o]

ok so far as i', able to read and understand that means s13 and r32 looms are different...but i could make a r32 control working in my ceffy if i rewire all that shit on the control?

so it should be possible (i'm not a wireing guru but i gonna try:D)

DAISU- That link for the repin site is down can you or someone else rehost the info?

I just got a DCC and trying to do this conversion...

PMing you as well!

[Jswljones]

K I think I got this figured out for the our cars but I rather just buy a harness from someone then re-pin one, dose anyone make one for me or know where I can get one??

[Nic_A31]

I've seen a couple of adapter harnesses on YahooJapan, can't remember the price, but pretty cheap.

[Jswljones]

I've been looking, if you see one post the link or PM i have a guy that I order through, thanks!

I know this is an old topic, but does anyone have a copy of that wiring diagram? The link posted earlier to a31cefiro.com is dead

For anyone interested, the Way Back Machine has that Japanese website archived with pictures, etc:

"Simply swapping the wiring of the harness will not allow it to function properly. For the outdoor air sensor and sunlight sensor, disconnect the wiring connected to CN1-11 of the air conditioning harness from the harness and connect the sensor side wiring to earth. For the indoor air sensor, disconnect the wiring connected to CN2-3 of the air conditioning harness from the harness and connect the sensor side wiring to earth. The connector PIN numbers listed here are the genuine A31 PIN numbers. To avoid incorrect wiring, check with a tester before wiring. Also, disconnect the wiring in a location close to the sensor. The disconnected harness side wiring will not be used, so be sure to insulate it."

Wish someone sold a conversion harness to just plug-and-play a Kouki 180sx digital climate control into C33/A31.

I'm decent with wiring but feeling kinda lazy about taking this on.

Edit: Did some more digging and found a helpful Minkara blog post about the conversion as well: https://minkara.carview.co.jp/userid/1831116/car/1360568/2284209/note.aspx

"After installation is complete or the battery is replaced, you need to go into self-diagnosis mode and set the internal air recirculation. The way to do it is to "hold OFF with the key on for more than 5 seconds, set the number to 5, then press 卍→C." ↑↑↑It probably won't make sense unless you actually try it (・∀・)."

Lol wtf
