Prop Valve Cheat Sheet?

Can someone point me to someplace that tells me what goes where on my 1LE prop valve. It seems quite different than the '83 I got rid of. Now that it is time to hook back up, I'm doing some head scratching.

Your 83 cast-iron combination valve may well have SAE threads; the alum 1LE valve will be metric. Double check that fitment. Here's a recent post that may be helpful where the lines are concerned:

Hi James-
Yes, I got that all my old threads won't fit.
I want to find out what should go where on the new Prob Valve. Then build out from there. I have already junked the old lines, except the front to back that goes to the rear axle. I will probably have to junk that, too.

Front bottom is the rear line.
Rear bottom is the pass side front.
Top rear is driver's side front.
