Silvia Digital Climate control Instructions................

Post by **Hypertek** » Tue Aug 09, 2005 7:43 am

So is this pretty much the parts needed or USDM equivalent?I just picked up a climate control from a buddy of mine with the sub harness.

"1. Japanese Digital Climate Control2. Plug to fit Japanese Digital Climate Control (from 89 Infiniti i-30)3. Sunload sensor* (from 96 Maxima)4. Plug for Sunload sensor*5. Ambeint Air Temp Sensor* (from 96 Maxima)6. Plug for Ambient Air Temp Sensor*7. In-Vehicle Air Temp Sensor* (from 96 Maxima)8. Plug for In-Vehicle Air Temp Sensor*9. Aspirator* (from 89 Infiniti i-30)10.Thermo Control Amp (from 96 Maxima)11. Plug for Thermo Control Amp12. Thermal Transmiter (from 89 240sx)13. Plug for Thermal Transmiter* = Not needed if you do not wish the AUTO function to work. AUTOfuction keeps interior at a selected air temperature.

-Extra Parts you need to make a new harness14. Plug for Intake Door Motor15. Plug for Door Mode Motor16. Plug for Air-Mix Door Motor17. Plug for Bi-level Door Motor18. Plug for Blower Motor"

Any other older model cars these parts might be found in? 90's M30, G20 Z32 etc?? Cuz newer stuff aint soo common in our junk yards.

Can i Just grab all the parts from a 89-94 maxima and it should work?

I will try & get a pic up of the harness soon, in the meantime, what's the best way to seperate the JDM DCC dash harness from the rest of the dash harness?

I remember you saying to as long as you had power to this harness, you were good to go. Where do you tap into it?

Thanks ALOT,Kb

I need a dash harness too, dammittttt, haha.

Hi,

I have tried your way in connecting up the digital climate control to my 180SX.

I manage to get everything working. cool!But... The problem I have encountered is that I cannot turn my aircon off???

After I have connected the 240SX harness (5 wire), the aircon just turn on and couldn't turn it off using the digital climate control. I suspected it is due to one of the wires on the 240SX harness. From the digital climate control, there are 5 wires but on the other side there is 6 wires. One wire is left unconnected. please help...?

Do you have any idea what happen?

Thanks

I tapped into the blue/red srtip wire running into the blower motor on the US harness.

dude ur awsome im actually gonna do this soon like in the next month or so but i was wandering did the 98 180sx type x come with digi climate because my friend has a clip in his backyard and i need to know if i can use his harness. much appreciate ahead of time

Post by **positron1** » Thu Sep 08, 2005 3:10 pm

I plugged the two big connectors on the JDM harness up, grounded the red/yellow, connected the green/white to the large connector and unplugged the relay. The unit has power, cycles through all the options but I cannot get the blower to work. Any suggestions?

Post by **sean8564** » Thu Sep 08, 2005 3:12 pm

can some just give a clifnote version of this

Post by **AZhitman** » Thu Sep 08, 2005 3:23 pm

No. Complex install, complex instructions.

Erich, great work!

I'll be making this into an article as soon as the Atlanta meet is past.

Post by **sean8564** » Thu Sep 08, 2005 4:34 pm

well you see i have all the parts and a R32 wiring harness which is the same as the S-13 all the way to the Blue sub harness wires. I just need a Step 1 and 2 and 3 write up and yea that looks good eric i want my coupe to bling like that even though I have no A/C.

Got the blower to work but now it will not stop blowing unless the ignition is turned off. WTF?

You have to have the Japanese blower motor speed sensor or the fan speed will not work at all; hince its always stuck in the full on position.

If anything doesn't work as of yet chances are that you fried the unit, I went through 1 before I got it right!

How do I just get it (the blower) to turn on and off with the DCC controls?

Post by **ericherm1** » Sat Sep 10, 2005 5:00 am

You must have the correct blower motor speed sensor. If your using the factory US blower motor sensor you will get the exact response as your getting now.

You can get the proper one from a Japanese clip, eBay, or 96 Maxima, and I heard that the digital control unit in the later model 300zx uses the same speed sensor and other sensors but not sure so if anybody wants to check it out to confirm this...please by all means.

Post by **scuba8085** » Sat Sep 10, 2005 8:39 am

I too have the same problem...I heard that you need a "sensor" for the blow motor.

The current manual climate control have a different sensor as compared to the digital one.

Could anyone advise how this can be solve?What sensor do we need to get?

Okay..thanks!!!

Post by **ericherm1** » Sun Sep 11, 2005 9:03 am

Look, the past page of questions can be answered by the first page of this thread along with pictures to help you out.

I would like you guys to first check those out before you ask these questions, I feel like I'm repeating myself by answering them about 10x now.

So please read the whole thread before you post...Please!

I'm not trying to be mean, just informative.If your confused then thats the time to post the question.Thanks,Eric

Post by **scuba8085** » Thu Sep 15, 2005 9:53 pm

Anyway, Just wanna check again...

Will there be a difference on the wire harness for the Engine type (CA, SR or KA)?

I have got most of it working except that the fan speed can be either OFF or On at high speed. The fan speed cannot be adjusted.

I have read from some other forum, they have mentioned that KA wire harness is different from that of a SR. Maybe the difference is in terms of the ECU it is somehow connected to it.

BTW, my is using a CA.

Any advise will be appreciated.

Post by **ericherm1** » Fri Sep 16, 2005 12:39 pm

The CA and SR share the same dash harness, the KA harness however was never ment to accomidate the eletronic climate control. The High speed fan relay (blue relay) is hardwired into the main harness on the KA. The CA and SR's are wired into the sub-harness that connects between the main and the climate control.

Post by **positron1** » Fri Sep 30, 2005 2:15 pm

I haven't been able to get a JDM blower motor speed sensor or JDM blower motor speed sensor plug to control the on/off function so I am trying to get the set out of a '96 maxima listed in the parts list on page 2. If anyone has the part numbers could you please post them? When I asked for these parts on a nissan website they gave me this link----

can some one poast a pic of the dash hraness and the blower motor speed sensor out of the car or pics of all the sensors i need have most of them i just dont know what the ones i dont have look like also do i need the jdm mode selector?

Post by **Hypertek** » Sat Nov 05, 2005 2:54 pm

I got these from a friend's r33 gtsm clip (i forget which r33, not a gtr).. I also got all the motor switchs from it,, but i forgot how they go..

but anyways, i got the digi unit wired in, and with that r33 fan sensor, the fan just stays on 24/7 when its plugged in.. Maybe its not compatible?? I got teh US main harness and fan installed.. but the digiclimate unit toggles thru the modes and lights up. Just no proper action.

Was I suppose to do some trick wiring to the fan??

Post by **Hypertek** » Sat Nov 05, 2005 2:55 pm

the r33 fan sensor is 3 prong.. is the silvia one 3 as well?

Post by **ericherm1** » Sat Nov 05, 2005 5:37 pm

The reason its staying on is because of the High speed fan realy. You have it wired wrong some how. Did you tap for 12+ at the blower motor like I showed in the pics on the 1st page?

Post by **ericherm1** » Sat Nov 05, 2005 5:45 pm

No, its a 4 prong sensor. That one in your picture will not work! Sorry

If you have the complete JDM dash harness and sensors then you are there and will have a much eaiser time with the install.

But if you just bought your digital climate control off of eBay or some other store and only have a cut harness then you need these parts to make your own harness and some other areas to find sensors that will work from other cars:

1. Japanese Digital Climate Control 2. Plug to fit Japanese Digital Climate Control (from 89 Infiniti i-30) 3. Sunload sensor* (from 96 Maxima) 4. Plug for Sunload sensor* 5. Ambeint Air Temp Sensor* (from 96 Maxima) 6. Plug for Ambient Air Temp Sensor* 7. In-Vehicle Air Temp Sensor* (from 96 Maxima) 8. Plug for In-Vehicle Air Temp Sensor* 9. Aspirator* (from 89 Infiniti i-30) 10.Thermo Control Amp (from 96 Maxima) 11. Plug for Thermo Control Amp 12. Thermal Transmiter (from 89 240sx) 13. Plug for Thermal Transmiter * = Not needed if you do not wish the AUTO function to work. AUTO fuction keeps interior at a selected air temperature.

-Extra Parts you need to make a new harness 14. Plug for Intake Door Motor 15. Plug for Door Mode Motor 16. Plug for Air-Mix Door Motor 17. Plug for Bi-level Door Motor 18. Plug for Blower Motor

You can use your existing US OEM harness but you must unwire the High speed fan relay ie. the blue relay beind the stereo and analog climate control.

The sun sensor is to detect differance in heat coming in through the windows to the ambient temp sensor that is in the center console.

-Eric

The 96 maxima came with digital climate control and analog. Doe the thermo control amp/resistor that we need for the Silvia conversion need to be the one for the digital maxima controls or will the analog resistor suffice?

Post by **ericherm1** » Sun Nov 06, 2005 6:44 pm

No, it must be the one for the digital controls, they work off different voltages so the analog ones will not work.

hello eric, i've been reading up on your DCC instructions for a few weeks now. i've hit a ditch and got confused on one of your instructions. on one of your post (page 2 middle), you mentioned the brown plug for the mode motor needs to be repinned, then couple posts later, you don't have to touch those and just repin on the harness. i followed your 1sts post of repinning & forgot to write down the original color order. i had a jdm brown plug also, so i repinned it matching the colors on the jdm plug. everything works except the modes dont match to their corresponding area when switched, i.e. press foot, you get defr, press defr, you get face.

i wrote down the order i pinned them, just wondering what order is yours at.

pinkblueblue/blackblue/whiteblue/redblue/yellowblue/orangexx-emptygreen/yellowgreen

thanks alot, any help would be greatly appreciated,don

Post by **ericherm1** » Tue Nov 08, 2005 1:30 pm

the colors are the same as the US harness just in different slots, you need to match them to the motor,... thats all..

Post by **nightxwing** » Wed Nov 09, 2005 10:48 am

hi eric, got everything working now, air mix motor, vent/foot/def control, and 1-2-3-4 setting on blower control. my car have no a/c so a/c and AUTO are not functional. but everything else works great, without any of the temperature sensors. just gotta take your advice on the brown harness(mode control) and rewire on the main harness. thanks again for the write-up. don
