Hey guys, need some help kind of quick. I am installing a B&M Supercooler as we speak. I have it all mounted and ready to run the lines but I am not sure which is the return line at the radiator. I have an 02 Tahoe 2wd 5.3, the code for my transmission is M30 on the sheet, is that a 4l60e?? Can someone please tell me which is the return line, the top or the bottom.......want to get this done. Thanks.
