i bought an s13 digi climate control which had a loom modified to suit a31...

it works... however... not entirely

lights up... but temp control doesnt work

fan does... and everythingelse... just when i adjust the temp it doesnt go hot or cold... just stays cold

loom is dodgey

I've considered attempting this with either S13 or R32 digital units, but I just don't have the time at the moment, and a few other more important issues on my car have priority (suspension/brakes etc).

I'd be keen to see the article, even if just for the pinout diagrams

s13 is a lot closer match (in fact if you have the digital sub-loom, it looks like it'll plug in straight up)

r32 would be a lot of custom rewiring

Is the page blurry or is it the photo?

I can make out most of the writing, but 18, 19, 20 are a bit fuzzy, looks like CN2-13, CN2-8 and CN2-7 respectively. Please confirm?

The jap symbols next to 8 of the pins I'm assuming means not used (or nothing connected).

Though the symbols next to pin 1 I could hazard a guess it means something like wire to constant 12V or something.

Only other thing is you have to rewire a couple other points on the S13 to make it work, I'm could only assume something similar would have to happen in the cefiro.

daisu are you a wiring junky?

i have my loom here... as stated above i can adjust the fan control and it lights up and everything works... apart from aircon controls, alternating which type of setting the aircon is on (footwell, head, footwell/head/ etc) and the temp controls - dont work... obviously some wiring needs to be fixed

i could send it to you if you want to use it as something to work off and make a duplicate for yourself?

only condition is you fix mine so it works :D

Only problem with messing around trial and error with the digital units, is you can damage the circuitry, then you don't know if the wiring it incorrect or not. This happens on the S13s when people plug the digital unit into their unmodified analogue looms, it lights up, i'm not sure if you get fan control or not, but it also permanently damages one of the functions like fresh/recirc or something. I can't be stuffed looking at the S13 guide right now.

I think I'll try on my own loom first, then when I'm sure I know what I'm doing I'll let you know how to do it.

Either that or softy will do it :rofl:

Hi All, I have just purchased a Nissan Cefiro 92 and the auto climate control unit failed first day and is stuffed. Before getting online I found that my r32 digital climate control unit plugs in by two of the three Ceffy plugs, however as the cefiro has a third additional plug it obviously won’t work without mods.

I have read everything I can find however I am not getting much of an understanding as to what wires go where to convert the a31 auto climate to the r32 digital climate control unit.

Is there a post i have missed that outlines in English solder this colour wire to that spot???

Any help would be greatly appreciated as I got caught in the rain and the fan won’t go to demist mode + air con won’t turn on so it sucks.

daisu has repined and soldered his to work but he wont/cant post up the pin outs.... the japanese scans just confuse me every time i try to work it out >_<

ca s13 unit will work

So i thought all s13 have 2 plugs not the three like i have on mine? have i missed some thing are ca 3 plug ?

    • What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
    • ...oops. forgot the TCU end...
    • No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here. 
    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
    • Got just the wing painted and fitted up to the existing boot. Big visual change and about time after having a GTR wing sitting in the shed since 2018 Headed up to Mallala with a quick obligatory stop in at Boliver OTR Oil control mods seems to have worked. I checked the catch can after session 1 and there was a dribble of water/e85 with barely any oil in it. After session 2 and 3 there was almost nothing and I stopped checking after that. so either great success or catastrophic failure/block of the external breather The GTR wing made a noticeable difference in the 160-185km/h sweepers. It was a very hot day for the cars at over 33C but the previously done cooling upgrade/ducting/water sprayers meant I never saw over 60C intake, 105C water and 100C oil and temps would drop back down very quickly once I shut it down. AD09's are a decent tyre but certainly and expectedly a step down when compared the the CR-S/AR-1 I have had on the car for years of track days. The handling characteristics of my car which I often describe using the Tony Hawks Pro Skater balance mechanic where either side of the center is understeer/oversteer was much more pronounced with no "green/safe" zone in the middle. However, imo it steers well/easily during oversteer largely thanks to the custom ACOSTAL front end. Enjoy a loose lap POV with my mate giggling away as a passenger.   Group photo for Peer Pressure Racing made it back home and gave it a wash Overall a great success compared to my previous two track days where i cooked the Starlets motor and blew up the new diff in the R32
