My current project: JDM Climate Control - Honda Prelude Forum

Forbidden · 07-23-2002, 08:04 PM

Well guys this is my current project

I just started installing it in the car this evening (for about 30 minutes) but I ran out of connectors (I'm planning on soldering the wires when everything will be done)

So far I wired the power, ground, recirculation motor and mode control motor (partially, that where I ran out of connectors)

Also I didn't hook the memory yet so is that why I have to press a button so I can see the stuff on the display?

It's gonna be fully functionnal soon, not in the next few days cause I still need a few parts but trust me on this it'll be fully functionnal

EDIT: For those who don't want to read the whole thread and just want the write-up, here's the link: http://www.jrcormier.com/prelude/jdmclimatecontrol.php

you get all the sensors when you bought it?
you'd be rich if you could do this again if ya know what i mean

ME · 07-23-2002, 08:08 PM

Very cool, how much is the JDM unit?

fourthgeneration · 07-23-2002, 08:13 PM

i hope you got the sensors too....

H22aPoweredBatMobile · 07-23-2002, 08:18 PM

please keep us updated..

evoandy · 07-23-2002, 08:40 PM

whoa sweet!!! where did you get your hands on that!? or more importantly, how much did it cost?! man, thats sweet. Keep us updated.... thats a really cool upgrade.

Z · 07-23-2002, 08:50 PM

make us a wiring diagram!

Forbidden · 07-23-2002, 09:06 PM

Well I bought the unit for 75$US shipped, it came with only one sensor, the interior temperature sensor but I'm not worried about that

I'm gonna continue working on it tomorrow after work at least finish the easy stuff and friday/this weekend I'm gonna do a little searching for the parts I need, I could get them all but I still need about 250$US in parts so I'm looking for better price and stuff

H22aPoweredBatMobile: I got your PM but I'm going to bed right now so I'll get back to you tomorrow, if I forget send me another one

jackal9220 · 07-23-2002, 09:08 PM

damn man...that looks nice...I hate when my friends with the new accords go "hey can your car do this?" ::adjusts the climate:: its annoying! nice JDM look man...

SikRedRX-8 · 07-23-2002, 10:45 PM

Will you be able to do a write up and tellus everything we need to do to get it to work? I am sure there are more people besides myself who are dying to know how. Thanks alot

munscher · 07-23-2002, 10:53 PM

yo, that is sweet... been thinking about gettin a climate control unit myself, but worried about how hard its gonna be to install... a write up would be perfect!

Devoe · 07-23-2002, 11:04 PM

Nice job! Looks so much better than the standard heating controlls. Where did you find the wireing schematic? I know it's allready been said, but a write up would be so nice. It looks really good. Big up's!

mario24601 · 07-23-2002, 11:05 PM

dust that dash...

j/k looks good

yellowh23a · 07-24-2002, 01:18 AM

I had a JDM cc in my car for over a year and a half, looks sweet but a total waste of money. I fooled with it once or twice... soder all the blk wires from them jdm & usdm harnesses, these are your ground wires, next soder the blk/yel wires from both harnesses together ... this is your power. The wht/yel wires will be memory. As for the rest? Donno. If someone could get their hands on a Japanese Prelude manual, that would help. It would have wiring diagrams in it. Would just need it translated ... no big deal. But good luck!

Forbidden · 07-24-2002, 05:47 AM

Yes guys I'll do a write up

I'll even make you guys a nice wiring diagram with the USDM/JDM differences on it (like where to cut/splice/add wires)

yellowh23a: I already got more than the power and ground done, I haven't connected the memory yet cause there are no wires for that in the USDM connector and I'm doing those first since they are the easiest, just cut from old connector and crimp with the new one

as for the dust on the dash it's cause I was waiting for spring to clean the interior of the car but since I was supposed to get my car painted I haven't done it yet

it's getting painted in a week and a half

SiR-P12eLude · 07-24-2002, 09:48 AM

post pics when done... keep us updated

brendon2k · 07-24-2002, 12:05 PM

So what else are you look for that is going to cost you 250 besides the rest of the sensors?

U.K VTEC · 07-24-2002, 12:30 PM

Good luck with the project Jean, I hope it works out well

Forbidden · 07-24-2002, 01:30 PM

brendon2k: well there's the air mix control motor, a transistor, water valve with the solenoid and stuff and the sensors. I think that's about it

U.K VTEC: Thanks man

You've been a great help

Forbidden · 07-24-2002, 06:28 PM

Well I continued connecting some other stuff, I finished the mode control motor and hooked up the rear window defogger and A/C, I can't tell you if they work though since my A/C was empty, and there's no fog in my rear window

I also removed my A/C condensor and heater blower, I think this is one step that'll make a line between the boys and the men

Right now I'm kinda stuck since I need a few parts to continue, I should get them this weekend or in the middle of next week

I took a few pics I'll try to put them online sometime this week

triumph · 07-24-2002, 11:41 PM

You are gonna be the man.

Forbidden · 07-25-2002, 05:22 AM

hehehe

though I don't know why I said condensor, I meant evaporator...

pter · 07-25-2002, 12:33 PM

Yeah, I was wondering how good a climate control system would be without A/C.

j92s · 07-25-2002, 01:41 PM

That is frikkin sweeeeeeet. Dont forget about us, document all the wires and stuff!!

BTW - dont listen to Forbidden, you dont need to dust your dash, you need to vaccum that SOB. LOL

Very Nice. Subscribe to thread:click:

E.G.W.W."92" · 07-25-2002, 08:23 PM

Hey i was just talking about that w/my friend. Will it be a problem w/a 92 2.3 si. Let me know b/c i do like it better. I'm also doing a h22 head swop soon w/turbo. I'm still thinking on NOS.

Eddie:

Forbidden · 07-26-2002, 05:59 AM

you don't need a specific engine to install the Climate Control, I also have a 92Si though I have an engine swap but it doesn't matter

E.G.W.W."92" · 07-26-2002, 07:59 AM

Cool, thats all i needed to know, besides is 50.00 a good price?

Eddie:

Forbidden · 07-26-2002, 08:28 AM

I paid 75$ for mine shipped so 50$ is a good price but there are other parts you'll need, I estimated around 250$ in parts, I'll only be able to tell you when it'll be done

E.G.W.W."92" · 07-26-2002, 08:24 PM

Cool kep me posted i will be getting it next fri. or so.

Well I kinda took the weekend off and found some info I needed. I just arrived about an hours ago and I'm now continuing my write up. Also on a side note my rear window defroster is working, I've had the chance to test it this weekend. so right now I have power, ground, recirculation control motor, mode control motor, rear window defroster, light switch (to dim the light when I turn my headlight on) and my A/C is connected but since my evaporator is out of the car I haven't been able to test if it turns on. I'll post a link to my partial write up soon and I'll keep updating it until everything is done.

marshdoggg · 07-28-2002, 04:57 PM

way to be dude, you will be a hero if you can follow through!

Forbidden · 07-28-2002, 08:11 PM

Well I started my write-up, so you guys can check it out at http://www.jrcormier.com/prelude/jdmclimatecontrol.php I took a few picture that I didn't include in there yet but they'll be there soon. You can email me for any questions, comments, suggestions, etc or just post that in here. My next step will be to make the blower motor work, then I'll play with the air-mix control then I'll connect the sensors and the rest of the wires (or I might do that first since I don't have all the parts to continue right now).

Hope you guys enjoy it and keep checking from time to time, cause I'll be updating my write-up as I continue to connect stuff.

yellowh23a · 07-28-2002, 09:23 PM

almost makes me want to get another one... gret job man!

aneurysm · 07-28-2002, 10:16 PM

I'm curious to see if the stuff from the CL works...I checked on stuff from a Legend and it was somewhat different. And from some comparisons at the Acura dealer, the Legend was the closest to it.

brad

Forbidden · 07-29-2002, 06:34 AM

I went to my "local" Acura dealer (3hrs away) this weekend and I checked in a Helm for the 97 CL and all 4 sensors were the same, like the resistance were the same, phisycally I have no idea, you might have to be a little creative to make it look good.

As for the power transistor, I have no way of telling if they are the same other than trying it but I doubt they are different

The biggest problem here is how to attach the air-mix control motor to the heater unit, if I can't attach it to it I'll just make a braket and attach it somewhere else near where it's supposed to be

Forbidden · 07-30-2002, 02:40 PM

Damn incompetent that works at the scrap yard didn't send me the right part, I ask him if he had blower unit cause I need some parts off of it and he said he could only sell it to me as a unit, so I tell him I take it and I just got it and he sent me the blower motor, I was so excited about getting it and be able to continue working on this and now this just pissed me right off!! I'll have to call them tomorrow, they better take that thing back

go pre · 07-30-2002, 07:51 PM

just picked up a jdm control unit off ebay for 50 bucks.. looks like I might try this conversion too. which parts are you positive that you can use from the CL so far? i'd like to start searching for some of the other stuff now while i'm waiting for the unit to get here.

redpreludevtec9 · 07-30-2002, 11:20 PM

are you saying you have to remove the evaporator and the heater blower or just one of them?

PreludeRacer023 · 07-31-2002, 12:02 AM

i want to put this in my car too....but heres the catch..I dont care if it works like it should ie climate control....just that i can turn the AC on and off..blow cold air..and control fan speed..and also turn on heat...but it doesnt have to keep the temp the same..do i need the sensors to do that..basically it would work like mine does now, except be digital and look better..let me kow...peace

You can use all 4 sensors from the CL, though I don't know how the 2 interior ones blend in the dash, I was supposed to get a power transistor from a CL but the guy didn't send me the right thing so I guess I'll have to call them back and wait so I'm not 100% sure about that... for the air mix control motor as long as the connection is the same it should work but I don't have that motor yet

If you want to control the fan you have to remove the blower resistor, the Helm says you can remove it without removing the blower but I tried and I decided to remove the blower it was easier, and you have to remove the evaporator to remove the blower, also there's a sensor for the evaporator so you'll have to remove the evaporator to put it in.

Well once you can control the air mix and the blower you pretty much done the hardest part, sensors would just be a few more wire to add. Though I don't think you'd need the sensors if you don't want the auto function but after you done the rest why not connect the extra wires for the sensors?

go pre · 07-31-2002, 07:39 AM

can any of these parts be had from the acura dealer? if so do you know how much they run? also, do you have any pics of what these parts look like? thanks.

Forbidden · 07-31-2002, 08:14 AM

You can check on www.acuraautomotiveparts.net for a 1997 CL, I think any model should have the parts, there's a section for the sensors, it has the 3 sensors you need in there, then there are a few parts in the heater blower section, the heater unit and the A/C unit I think, parts go up to about 250$ I think. The problem is that if you buy the parts new from Acura you might not have the correct connectors or stuff and parts like the transistor don't come with any wires on it, I'll put a diagram of the parts in my write-up soon

MR.CLIFFORD · 07-31-2002, 08:12 PM

hhehehheee.... now you have done it. You won't be able to find a JDM climate control unit on Ebay for less than 100 bucks. Awesome work. YOU DA MAN

Forbidden · 08-01-2002, 06:39 AM

I wonder if they'll go up once I finish everything up

go pre · 08-02-2002, 09:06 AM

do you know what wires hook up for the mode control motor yet?

Forbidden · 08-02-2002, 10:10 AM

yes it's wired already and I explained it in my write-up at http://www.jrcormier.com/prelude/jdmclimatecontrol.php
