you're going to want to turn that thing around, the usb port is on the other side. i have perfected the efisource install.lol. also if you're going to use the megasquirt to control your cooling fan,( highly recommended) you will want to run the fan wire through the harness before you get to far into your install. the efisource directions on the pin location are all the directions you will need. i have an awesome tune up for anyone running eagle heads on an early engine with a decent camshaft too.
