Linear drain
There are dozens of different types of linear drain. Unless you can tell me which type/brand you have, I can't really help, as ther are sveral different ways of effecting a connection. Have a read of the Linear Drains page for details of the most common methods.
However, if you don't understand the layout of the drains, and are not sure how to make a connection, I have to suggest that you might be better off asking a drain specialist or a competent groundworker to undertake this work for you.
