dual zone HVAC pinout

Recommended Posts

Does anyone have a pinout diagram for the 2005 - 2009 USDM dual zone HVAC system without navi? I'm talking about the two connectors not relating to audio. I think they're i17 and i88?

 

 

 

I have a dumb 'because I can' project. I have my old head unit from my OBXT, and I was thinking of tacking it to an arduino or RPI to use the head unit as a way of controlling some blower fans, maybe audio output, etc, for my sim rig. It's dumb as hell, but I got parts around that are taking up space and I have no intention of using them again in the car, so why not. I guess it would also work to reverse engineer the HVAC control system, I guess.

 

 

 

What I do have already is the audio connector courtesy of David Carter (ae64.com):

 

 

 

Audio connector setup:

1: Illumination+ - (+12v ‘switched’)

2: RF speaker + (if using a tweeter, connect in line)

 

3: LF Speaker + (if using a tweeter, connect in line)

4: RR Speaker +

5: LR Speaker +

6: +12vdc memory (+12v ‘constant’)

7: Illum- (Pot to gnd)

8: RF Speaker –

9: LF Speaker –

10: +12vdc accessory (switched)

11: GND

12: RR Speaker –

13: LR Speaker –

14: power antenna: (No Connect)
