After searching like crazy and not finding anything. I need to know some info about the three holes on the rack. which one is feed, which one is return, which one i can plug. Im running a custom MR2 Electric PS pump setup and only need 2 of the 3. There are 2 that are very close and one all by its lonesome. I will be doing a full write-up and how-to on this setup. Any help will be much appreciated. The car is a 89 GTUs

I really don't think it's that simple. If you need a 2 line PS rack, get one from an S5 NA.
