I found another write up. This one uses analog air mix door cable instead of metal rod from JDM s13, so you can still do it even though you only have the motor.

Anyway, I have some pics to share. Went to junkyard and had a chance to take some good pics.
Look at the box in the middle and you will see the cable under the box. That's air mix door cable.
I found another box that's under the golve box and attached it to the center one like this.
Air mix door linkage. I moved it back and forth and door was maving this way.
This is a box that you see under the glove box. Blower resitor can be found in this one.
Side view.
This is what broadfield was talking about. It was already touching the line like this. It's a thin line, so you can carefully bend it. You can use back of screw drive and push it. No need to grind down the JDM resistor. Coorect me if I'm wrong.
I looked at it carefully, but I still couldn't find where aspirator hose goes to. Can anyone point out where it goes?
