Yes.

[SilviaK]

Does anyone know about installing the Digital climate control into a '90 Silvia K (RHD)??The car comes stock with the Automatic climate control and all of the sensors in place.I have only been able to find info in regards to the USDM 240SX.Any and all help is greatly appreciated.

I did take out the wire and put it in the other connector. I then plugged the plug into the matching one. Is this the correct way to go about it?

[RPS13.5]

Which GREEN/WHITE wire? Any picture where this wire coming from, and why is conected to the power? and the only GREEN/WHITE wire I know is the one that goes to the AMBIENT sensor.

[RPS13.5]

If you already have an ANALOG CLIMATE CONTROL into your RHD S13 and replacing into an DIGITAL unit; basically you just plug and play, and make shure you have the DCC unit main harness, so that you can see the difference between this two unit.

The difference is:Analog CC have 3 plugs harness at the back of the Analog CC unit > 2 BLACK & 1 WHITE plugs.Digital CC have 2 plugs at the back of the DIGITAL CC unit > 2 BLACK plugs. Also have a 1 PIN plug which is RED wire that located at the DCC main harness.

You will see the difference...If I still remember everything should plug in the same except that 1 PIN plug - RED wire needs to rewire. Some how on this first page of this forums have some examples how to wire this 1 PIN plug - RED wire.

I have the DCC and a cut DCC side of the harness (two white connectors). I remember looking at the colors and not seeing much resemblance. Also my 2 factory pin connectors (black) are the same as the DCC, except they don't plug right in. Some modification to the pin housing "guides" would have to be done to get it to plug in.So after all is plugged in, what do you do with the large connector?? Leave it out of the way?? I just want to have all my info straight before i start modifying the stock JDM harness in the car.

the green with white wire i am talking ablout is on the second pic. down on beatupsx's guide zerothread?id=160285

[SilviaK]

Also, I don't have just one plain red wire...there is a red/black and a red/blue. Does this single red wire run from the DCC to 12v constant??

I pulled my Auto climate control out again, and i'm pretty sure it does not plug and play. The large white connector is for mode selection (defrost, bi-level, etc.). Also the pin locations do not match on the 2 black connectors vs. the 2 grey connectors on the DCC. I'm thinking I might need the complete harness. All of the sensors and flapper motors are in place, so its just wiring.If anyone could confirm or not, please do.

The only parts of my digital climate control unit that light up are the center LCD display and the right side of the unit with the OFF, AUTO, DEFROST and RECIRC lights. The blue and red arrows below the LCD unit did light up but stopped about a week ago. I'm thinking that I need to swap the small bulbs screwed into the back of the unit. Any ideas...does anyone know where I can get those small bulbs? I tried AutoZone and O'Reilly's but no go.

I finally got the entire climate control unit to light up. I could not find any bulbs with the white bases to fit the climate control unit so I pulled some blue base bulbs from the bezel buttons that I replaced(Headlight retract and Defrost). I carefully removed the bulbs from the blue bases and put them in the white bases...now the part of the display that did not light up now works perfectly. Thanks to Dammitboy for the hookup on the blower motor resistor and climate control sensors!!!

I just got a complete dcc and i wired it up exactly how it says to in the first post of this thread.zer...age=1 Here is my problem. As soon as i key on i get full blast blower. This will occur with or with out the dcc main unit plugged in. Any ideas on where to start looking?Quick recap on how i have it wired. Complete us harness with jdm dcc sub harness.Positive wires:All three positive wires are on the dcc sub harness:1. Green/White stripe, on small white 7 pin plug, this needs to be ran to an Ign+. This wire can be moved to an empty spot on large white 16 pin plug 2. Blue/Red stripe, on the small white 7 pin plug, this needs to be ran to a Ign+. I tied this wire into the large Blue/Red stripe wire on the blower motor.3. Red, the plug with a single wire, this needs to be ran to a constant +12v. I tied it into the memory wire for the radio, Red/Black stripe.Ground:Red/Yellow stripe, found on the large white 16 pin plug on the usdm harness, this wire needs to be cut and the side that goes to the dcc needs to be grounded(one of the bolts on the shifter boot works great), tie the other end of the wire out of the way.

After i rewired those 4 wires i just plugged everything in. Swapping out the uspec thermo control amp for the jdm one. Also both blue relays are plugged in.

I get every function to work except my blower running at full speed even with the dcc control unit switched off unplugged or at any selected speed.any ideas what i did wrong. I cant seem to figure it out.

2. Blue/Red stripe, on the small white 7 pin plug, this needs to be ran to a Ign+. I tied this wire into the large Blue/Red stripe wire on the blower motor.

Try hooking that wire to another Ign+, some people have the same problem with it connected to the blue/red wire on the blower motor plug.

Also you said you swaped the thermo control amp, but what about the blower motor speed controller?

Well i never tried hooking it up to anouther ign+ source but i did completely disconnect it and the blower still runs full blast. So unless the ign+ tell the motor to stay off i dont think that will do it. I will try and run it directly to the batt. as a temp solution but i dont think it will do anything.

BLOWER MOTOR SPEED CONTROLLER! i never changed that. What does it look like. Is it just a rewire or do i need the jdm one. If this needs to be change than that is where my problem is. Again all i did was rewire the 3 pos. and 1 neg. wires according to your writeup and switched out the control amp. I though that would get me all the postitions, and blower control. I didnt mount any sensors or the elec. temp control box thing that replaces the manual slider. Also i had the complete harness so all the sensors when plugged in they just weren't mounted.

[driftin8ez]

ok new update. Still need a little help. I got everything mounted. Ran the diagnostics mode and everything checked out. All sensors working. temp, and location select working. When you turn off the unit the fan turns off. However when the unit is on i only get one speed. Full blast. Besdies that its working 100%. So what do i need to get the fan speed working? is it that blower motor speed controller from a maxi with dcc or is something wired wrong?

[ericherm1]

I assume you read the whole post... many people have this problem. The only way that I have corrected this is to swap the Blower motor speed sensor:

Please re-read page 4 of the post:

zer...age=4

I know how frustrating it is to do this for the first time ... but you have this and a couple other resources. All you have to do is calm down and read the entire post.

Try this first and it they don't work then your out of luck from my point of view. This is the only way I have gotten them to work correctly.

[driftin8ez]

I did read the whole post. My head was spinning by the end. LOL. and it was frustrating to say the least. Mounting the mix door motor was by far the hardest part. Anyway ill try and find that blower speed motor and go from there.

[driftin8ez]

ok so i went to the junkyard and got that black box thing from a 92 nissan maxima with the dcc. It had all the other sensors so i know the car had a dcc with auto. So i pulled that black box off and spliced it into my car. Still have no control over the blower. Its on or off thats it. What am i doing wrong. I have the amp with the heatsink from a jdm clip and i have the black box from the 92 maxima. I included a picture of my set-up maybe some can help me with what i need. Do i need something else as well?thank you

[driftin8ez]

i have access to a bunch of q45's j30's and maximas at the junkyard by my house. I want to take a trip over there in bout an hour so if anyone what else i should pick up for my climate control let me know so i dont have to make so many trips.

[driftin8ez]

Try hooking that wire to another Ign+, some people have the same problem with it connected to the blue/red wire on the blower motor plug.

you where right the whole time. I moved this wire to the ign+ on the radio harness and everything works fine now. Thanx to everyone that helped.

[ericherm1]

Be sure to check your voltage's becuase the radio curcuit is rated for a lower V than the Blower motor....

we don't want any fires now..

[driftin8ez]

yes we definatly dont want that. where is there a better ign+ source to hook it up to? Could i connect it to the blue/orange wire in the hvac harness?

[ericherm1]

Test the radio curcuit with everything on.. acc on full. Check it at the fuse box to make sure its not excceding the 10 or 15 amp rating.

Hello guys,

I just who here has a SR swap and a working air conditioner??? yeah cool a/c???

Anyway.. My other question is in the climate control in the picture where you see the 32 degree... which is the sensor that reads that temperature??? the ambient air temperature sensor or the sunload temperature sensor????

I havent started the swap yet.. still gathering parts..

[kouki munster]

The number that is displayed is the set point, the only way to read the inside and out side temp is, is to get into the diagnostics mode.(iirc, how to get into the diagnositcs is on the second page of the thread linked in my sig)

[needforjdm]

To anyone who has done the conversion sucessfully,

I am trying to do a conversion from the JDM analog slider type to the jdm digital climate control. The jdm color code is different from what you posted. Anyway, I have attached some photos for your verification:-

these are the 16wires plug from the JDM analoge climate control - slider type. does the color code match up with the USDM? - photo #1

[needforjdm]

6 wires type - the black wire is grounded to the chassisI believe the color code for the usdm is pink

[needforjdm]

Attached photos are the brown connector to the bi-level motor.. which needs to be re-pinned according to eric's post..

I have compared the jdm dcc and the analog slider type.. the wire configuration is the same which i dont think need to re-pinned.

anyone have the photo of the usdm brown connector?
