Line-lock install questions (no ABS)...

Consulting the experts on how to install a line-lock on a '99 GTS.

There are 2 brake lines (primary and secondary) coming off the brake master cylinder that lead to the combination valve or proportioning valve. If I'm not mistaken, the one closest to the brake booster is the primary line that controls the front brakes.

If so, the primary line is the one that needs to be disconnected from the master cylinder and combination valve to be replaced with new brake lines, 2 new lines to be exact. One line from the master cylinder to the line-lock, and the other line from the line-lock to the combination valve.

I made a drawing of the complete install, which can be viewed here:

I would appreciate if someone can please confirm...
