Proportioning Valve Question

[hsdropout]

I have searched for a diagram that might provide info but can not find. Am I correct in assuming that the threaded orafice right of the green fitting (see photo) goes to the front disc brakes, and the coupling at the back (left of the pink fitting goes to the rear drums? Or is it the opposite?
I am assuming the fitting under the rubber cap on front (right side) is a bleeder valve?
Any help to describe which is which would be much appreciated. Thanks.
It seems fairly important that I get the braking system installed properly.

You are correct about the line location, but the rubber plug is the valve the activities your brake light if you loose pressure at one of the lines. When you have sudden fluid loose it slides forward or back and grounds the brake light switch. If I was at school I could provide a better diagram. You shouldn't need to bleed the valve but if you do you just crack the lines open a turn or two.

Thanks rootbeer.
I had read what the electrical switch was for but still not sure what the rubber cap at the right end is for.

If you are asking about the rubber cap, it is a protection from the elements to keep the slide portion of the switch clean, like RB said there is nothing you need to do with the plug, except keep it clean!
