Master cylinder and prop valve install questions

I'm attempting a disc brake install on my 66 mustang. I've got the discs installed, but I'm caught up on the master cylinder and prop valve install. Does anyone have any pictures or diagrams of where/how to install the prop valve? I'm assuming the hard brake lines are coming from the stock distribution valve located on the side of the engine. Where did you install your prop valve? Pictures would be a great help.

I could show you where my prop valve is, but it probably won't help you (mounted next to driver seat). It usually is placed by the MC where it's easy to access for adjustment.

Install it in-line on the rear brake line.
