You need the following:1) fan control module2) temperature sensor3) recirc door motor4) all wiring between these and other components5) anything else that might be different, IE other door motors6) SR ECU to run the A/C compressor

Good luck acquiring all that.

i have the digital control, the temp sensor, wiring harness, and what looks to be two door motors one of which plugs directly into the wiring harness. but if you guys have a jdm wiring digram that would be a big help. thanks

Can you cite this?

From looking at the wiring diagrams, all it appears to be getting from the ECU is the throttle position. The analog unit needs the same information, I would think it would wire right up.


The cycling of the compressor is ECU controlled by input from the triple pressure switch. In addition, the IACV-FICD controls idle up when the A/C is engaged, again ECU controlled, and at WOT the A/C clutch is disengaged. Since the control head inputs are different, you need the SR ECU to piggyback the KA ECU, or you can reprogram the KA ECU to allow for the right inputs. That is what I've been told from a former 240.org list member who got it working in his car. I had concerns since I have an S14 climate controller, but I don't have A/C so it'll be a little easier for me, once I get a clip to work out of. The S13 and S14 might be different too, but you at least need the rest of the parts to even get started.

I have a 1995 and the AC clutch does NOT disengage at WOT. It does on some cars, but I don't think these. I'm glad it does not because it sux when it does.

I don't see a connection between the between those two, but I don't see a triple pressure switch, either. There's a double pressure switch, though, but it's not connected to the ECU either.

I don't see that one, either.

I'm not calling you a liar, I just don't see the connections you're describing.

The wiring diagrams are here for anyone who wants them.


Those are diagrams for the SR motor, with the SR controller and SR ECU. In a KA, it's different. I see that through that diagram though that you can make it work that way, but you still need those parts listed to do it. The KA ECU couldn't control those items unless it was programmed to do so. The only other way is to let the compressor run constantly and not cycle.

The pinouts on the KA ECU to the compressor and the SR ECU to the compressor are the same. The connection is only to a relay, so it isn't like it's sending data, just an electrical pulse.

Of course, we're both talking out of our asses, because neither of us has done it. :) This is a fairly common question, it's a shame we can't seem to find anyone that's done it.


The relay, the triple pressure switch, the FICD, all are ECU connections. But you're right, I haven't tried it, and won't. A/C is useless weight.

i could use the help because i'm allright with the mechanical stuff but when it comes to wiring i havn't had much experince, except for stereo crap. The only problem is I don't know when i'm going to do it cause i'm pretty busy lately i was just going to do iy when ever i got a chance

hmm ok, here's a couple more...

I'm guessing the temp probe is seperate from the head unit soo, where does it mount? in the dash? in the console bezel?

Are those motors missing from the US 240? I don't think the US controls were cable-type (I maybe wrong), meaning even the recirculation flap motor should be on the US one already.

Looking at the ebay pics...the pic where the guy is holding up the head unit...is that harness seperated from the box of stuff? If it is cut, as far as we know, all the harness that is needed?

the temp sensor is just about the size of a nickel and you can probably mount it anywhere just by drilling a hole my 240 IS cable type and i have the motor, thats the one that plugs into the harness and then another motor that looks to be a vent door opener but i'm not sure where in the dash it will go (of coarse i haven't tore my dash apart yet) The harness is separate from the box of wires but it doesn't look to be cut

I have the control unit and a partial harness.. but i am missing most all else.. I'd love to see a writeup/final parts list when you get done.

thanks for the reply. I don't even have a 240 yet so I was guessing about the cables. Yeah that was very helpful!

same as CyberKreig, I'd love to see a write-up!! :)

Anyone get any where with this.

More after an exact parts list, as i have a UK S14a and hope that most of the loom is already in it (Its a SR20DET from the factory).

Thanks
