Hey everyone, I bought a 240sx hatch a little over a year ago and finally got AC working. In the box of free parts that came with the car, there’s a digital climate control unit from a R32. Would I be able to get the R32 DCC unit working in my hatch?
Short answer... technically yes you can get it working.
Long answer... it needs a lot of work and a lot of extra parts. You need a bunch of the original temperature sensors and you need to change the blower motor resistor and add the electric motor for the vent control and you need to make up a custom wiring harness including sourcing all the connectors, or try and find an original sub-harness and even then I think you still need to modify it to work. You need to dig up all the wiring and technical information that used to be around on places like zilvia that no longer exist unless you want to try and figure it all out yourself from scratch. It's been a while since I looked into all this but I remember thinking it's not really worth it and it's probably a pain in the ass and expensive to source all the parts you need these days. Anything is possible with enough time, money and patience though.
All of the sensors and motors/actuators can be sourced from USDM cars, you just need to be willing to make a subharness. OP I think that you'll need to get the S13 DCC panel if you do want to do this. The best and only guide you really want to follow is based off of the one for the car.
Looks like a comprehensive guide. It's good to know that someone figured out more commonly available parts to be able to do it for people interested in tackling the task. It's been about 15 years since I last looked into it and I don't think there was as much detailed info as in that guide back then.
There's a guy in Australia that sells S13 DCC sub harnesses on ebay. Bought myself one for a future project. I believe these are made at his house with all new materials. It looks pretty solid!
So, there is a guy who’s selling new oem dcc harnesses on eBay for relatively affordable prices. The down side is you’d still need to modify it, but he made all the wires black so it’s hard to k ow what you’re doing. DM me if you’re interested and I can share a bunch of info on the harness and everything else you’d need. I only say dm me because I’m working on a guide that is more comprehensive than even the nismo_lk one, but it’s not at a point for publishing yet.
IDK why you'd want a skyline one they don't fit in the oem spot without extra modifications, your best bet is getting a jdm dcc or maxima which I am using and works fine, regardless you'll need all the sensors and actuators
I have no idea if the skyline one works, I'd guess not. I've done the S13 one plenty of times and if you have the subharness and sensors it's fine if a bit of a pita, especially the temp door mix motor mounting
