Proportioning valve inputs/outputs - 10/30/2007 6:49:14 PM

I am replacing the brake lines on my 99 Silverado on account of failure of one of the lines due to corrosion. I can't believe there isn't a recall on this but that's another story. (The dealer acted like it wasn't unusual when I called to inquire, but I have owned 40 vehicles in my life, many older than this and I have never had a metal brake line fail.)

Anyways, I am trying to trace the lines back from the proportioning valve and it's kind of a pain. Can anyone help me identify the which inputs go where so I can just cut them all off...it will save some time. There are three lines on the top and two on the bottom of the valve body. One goes to the rear of the truck (top right I believe when facing the lines) and then two go to the master cylinder and two go the front brakes but I don't know which is which.

Any other tips or tricks on this DIY project appreciated.
