Automatic A40 Cooling Lines Pressure side?

Need to know which cooling line is the pressure line and return line for the radiator cooler.
Can not find a Toyota shop that knows :screwy:
I want to make sure the radiator cooler is first, then the additional cooler I'm installing, ( :nono: don't want to reheat the oil to 80c after cooling it in the external cooler)
Thanks

I don't know, but I would figure it out by disconnecting the lines, start the engine, and see which one pissed ATF.

I don't think the A40 model number is correct, mute point.
I was just want to plumb it all in while I was putting the new engine in.
Thanks for the reply Brian,
