I don't quite remember exactly. I think it was the bottom one was the return to the tranny.

Simply cut that line and have someone crank the vehicle. If you fluid spits out you know thats your line.

The top line in the radiator is the return, tap into that one.

thanks for the help the top on is the return to the tranny... I installed the cooler last night I'm driving today and I'm losing power so I pull over and what do you know a hose busted... I think it maybe have from using a fuel line I got from atuozone cuz I didn't have enough hose that came with it so I lost all my tranny fluid... do anyone think I may have some tranny damage now I drove on it about 6 miles?

oh I forgot to ask am I supposed to tap in the line going to the tranny or from the tranny I tapped in the one thats going from the tranny

Pull the top tranny line on your radiator connect that to your tranny cooler, this will be your return line to the tranny. Then connect your other line on your tranny cooler back into the top of the radiator, this will be your pressure or input from the radiator to the tranny cooler. That's how they are from the factory. Basically the radiator will heat the fluid up to temp and the tranny cooler will cool it down a bit before returning it to the tranny.

do you think I caused any damage?

One good way to tell. Fill it back up and see if it still moves. Unfortunately I would bet that even if it does still move that some damage was done and you have shortened the life of your tranny. So pray that it still works and start putting money in the new tranny fund now.
