There is a tool called points to line in data management that does this.

You might to use "x tools" that its a arcgis pluging

you can create lines from an attribute that indicates the order of entry points

You can create a line feature and join the points, in attribute table you can see the information about line.

Hey, I know that I am very late, but your question is my problem now and I still search about the solution, but I used the OD matrix to connect 166 points together.
