Automatic dual climate control harness

Thank you @Chaetagnath, @phanguy, @DustinS. I was able successfully execute a fully functioning Dual Climate control swap.

That is extremely impressive. I think you might be the first to do the full dual swap and build your own harness from scratch. When you get a chance you should post any tips you learned along the way for others, particularly where you sourced the parts.

Or at least how you got the dash bar out haha. I have everything I need to finish full dual, but I couldn't get the dash bar out.

As mentioned earlier post, you disconnect the steering wheel and the two bolts, also one that secures it to the bar,

What is not mentioned in the write up but perhaps in the manual is that you must pull outer sleeve out.

Then there is one bolt that secures the steering column just before the u joint thingy. You have to open that and pull the column out completely.

(update: Also its kind of difficult to put the column back over to the shaft. The best way of inserting it back is to pry it open with a screw driver just enough to so it slides back. The slit is right by the bolt you would take out on the last step, which you cant miss.)

Note that once you disconnect that your steering might go back together straight. You might have to adjust steering wheel to make is straight and might even have to run Techstream VCS normalization, if the traction and ABS lights comes on.

I got about that far and wasn’t really excited about pulling that all apart. Those bolts are quite a big pain as well. Guess I might try again as engine/transmission are out for another rebuild. Thank You.

The only thing which is not right at this point is, as soon as I turn the dial to anything besides low, its blowing super hot air. It seems like there is no temp modulation.

Did you have such a problem at all?

[DustinS]

Make sure the Temp sensor is plugged in and tube is attached. Mine had fallen off somehow. Although I don't have A/C yet as I am LS Swapped, if I had mine set at anything less than "HIGH" it would turn the heat very low and get cold in the car.

You may have to try and calibrate the motors, or set them a certain way.

Hey guys! i just saw this post and im really interested in converting into true dual climate control system. so i just want to make sure if this is correct. We need need these items?

Driver side temp control servo: SU003-02045
Damper control servo: SU003-02044
Screws for the servos (need 5 total) SU003-02113
Blower transistor (73533AJ000)
the climate control panel: 72311CA061
temperature sensor: 73730CA020
the hose assembly for the temperature sensor: 72313CA010

Connectors:
90980-12155
90980-12554
90980-12248
IL-AG5-7P-S3C1
90980-11918
90980-11909
90980-11135
90980-10796

and wiring for these connectors?????? o.O?

On occasion when the external temperature is cool, there is a large difference between the low setting and the next up on the auto (65), so it blows warmish. However on normal hot days it is pretty good at blowing cool air throughout. Maybe try adjusting the temp sensor location.

IL-AG5-7P-S3C1 quick look and I see that you have not included a corresponding male connector.

[Drgn5213]

i didnt noticed it at all till u point that out. Thanks. So my question is, with that list and the corresponding connector (IL-AG5-7S-S3C1) are what i need to do a complete swap? If so, i would start duplicating that harness.

Quick fix, I figured out what the problem was, pin from temp sensor was not making connection with the back of the control unit. It needed to be pushed in more. These AMP connectors are little tigther than the OEM connectors. 18 Guage wire is too thick and 22 Guage is to soft to fit them in. I guess best wire is 20 awg.

Its working good now.

When it comes to the Relay socket regular socket relay is not going to work. I ordered one and no good. So I 3d printed one relay socket, used 9mm male and female slip on connector for the thick relay terminals on both end with a wire in between.

The original relay socket Randy used is only available in Europe. I probably should have ordered it, instead of relaying on eBay relays. At the end 3d solution worked just as well.

Honestly, you guys are awesome

im going to revive this old thread. Someone on one of the facebook groups claims that on the 17+ 86s (assuming the same for brz premium?) they run same exact wiring harness as the one used on the dual climate control equipped ones. Essentially if this is true, then i wouldnt have to go through the trouble of putting together a new harness for at least single zone climate control. Anybody know or willing to help me do the research to see if there is any truth to this?
