JDM Climate Control
I am interested in putting this in my cousin's car.
I understand what this type of system needs to function:
1. sensors (sunlight, ambient temp., cabin temp., A/C Evap. temp., and Cooling System temp.),
2. Air Mix Control (vacuum or electric actuated)
3. Transistorized blower control (with a High Pass Relay)
This is not my first time doing this sort of thing, my 5th Gen thread.
In my car (a 1997 Honda Accord EX-V6 w/Leather), I went from my stock US 5th Gen Honda Accord climate control…
To a fully operational digital climate control.
But, I do have some questions with regard to installing the JDM equivalent in my cousin’s car.
On the Accord 2.0 Si, was the Heater Valve vacuum controlled? I know that both the Vacuum Solenoid and Electronic Auto Mode Motor Assembly use a 5V reference for position and are completely interchangeable in some situations; it really depends on the HVAC design. I simply would like to know more about the original design so that I can make an educated decision as to how I will design my adaptation to my cousin’s 1990 Honda Accord EX Sedan.
For everyone that has a JDM climate control in a US Accord and has it functioning properly, did you guys and gals use a JDM Transistor, or did you guys try any of the other Transistor Assemblies that came with the Acura Legend, Vigor, RL, TL, TSX or MDX.
Can someone post a pinout for the actual climate control unit? Or at least let everyone know how many connectors go into the control unit and how many pins it/they have? I know of only two designs: a single connector design (found in the US 1G CL), and a dual connector design (found in the 5G RHD Accords with digital climate controls). The colors of the wires are identical in both, but can often lead redundant sensor input if not wired correctly, e.g. using a Heater Core Sensor and Cooling System Temperature Sensor, at the same time.
Lastly, what color is the display on the JDM climate control? Blue-green? Amber? Did the Accord 2.0 Si come with both colors as options?
This should be a fun swap. After doing my car, I felt like I had installed a radio with alot of wiring; so I know what to expect. I got mine done in 22 hours, it was a blast. You guys should see more of me on this site. My cousin is Ford guy (ex-Mach 1 owner), but ended up with the Accord recently. He does not know much about them, but is learning from me everyday; as I learn from you guys and the Helms manual. Right now, he is letting me play with his car until school starts. In April, I threw rear disc brakes on the car; it took about 30 minutes to get it out of the junkyard and 2 and a half hours to install it in his car. Last weekend I did a 5th gen upgrade to the trunk space.
