When you get your cooler, the instructions will tell you how to tell which are the pressure and return lines for the transaxle. Ignore that part. You'll be connecting the cooler to the transmission lines at the top of the radiator on the passenger side. Mount the cooler in front of the radiator on the passenger side. This is the same location as stock SSE'* and SSEi'*. Because I had a stock cooler already there, and added another, things got kinda tight with the hoses. I found it much easier to remove the headlight while working on routing the hoses. You may or may not have to do this for an SE.
Make sure to check your tranny fluid level after adding the cooler.
