Did they not pack the instructions in with it? Should of had a few of 3D drawings and another paper with directions?
Port 1 is the first piece that drops down from under the top for the port. It should have on rounded over side and the port 2 will L off the from behind port 1. Port 2 should have one side fully rounded over. If you need some help or have questions just call me and I can help you out. Fastest way to get it worked out for you?
