Hey Guys,

one thing since my 1JZ swap in my sc400 that i havent gotten working is the heater valve. the FSM says that there is a power wire from IJ2-2, which is easy enough, but the black/yellow PWM wire that grounds into the AC unit i cannot figure out where it goes. There is an II1 and IR2 plug that it supposedly runs through.

has anyone had to figure out that black/yellow wire before?

i am also going to see how much hotter the cabin is if i simply let the heater run thru the heatercore all the time.
