very impressive write up. Thinking about doing this, if you were to do it again would you just use an automatic thermistor in place of the manual thermistor and forgo the converter you built?
Yes, I would. I built the converter because I didn't want to disassemble the AC system. Well, I did a Turbo Conversion and all that stuff had to come out anyway so when I put it all back together, I used an automatic thermistor. In addition, you have easy access to the AC Evaporator core through the air filter door. You can just push an automatic thermistor into the AC core through that access point - using that and leaving the manual one in place. Just be sure you install it in a place that is not being rubbed on by the cabin filter (if you use one) - you could wear out the aluminum in the core (it's very thin) and create a leak.
I'm in the middle of doing this myself and found your thread. I'm swapping an STi motor in so had the harness all apart anyhow and just added in the Auto A/C stuff.
I'm wondering about the venturi tube that goes to the side of the heater core housing...are you positive there was a hole cut out on the auto a/c version? When I pulled mine from a junkyard I neglected to check...
I ask because I wonder if opening that hole up would cause false high readings (as it's connected to the footwell heat area)?
I think I'll answer my own question here... There's a k type thermocouple at the front panel of the Auto A/C unit. The airflow from the foot area flows through an annulus where the center section is connected to the front panel. So it basically acts like a venturi and creates a low pressure zone to make air flow past the thermocouple up top.
So hole saw it is

as soon as shit opens up again, I'm gonna hit up the junkyard and pull everything from an 2000-2004 outback llbean to see if I can make this work in my 99 outback.
