brake issue

hi. i own a 63 sedan deville. i just converted my front end to disc brakes. i used the assemblies off the 69. everything is about finished, i wanted to know if anyone knows about the braking system on a 69 cadillac. on the proportioning valve, (brass box with little nipple on it for brake warning plug) anyway on that valve i have two lines that obviously go to the master.. on that same box i have two ports.. one is a 1/4 in female, and the other is bigger,,,, female plug. im curious which one trials to the front brakes, and which goes to rear? also on the master which port is front, which port is rear? and i think last but not least, once i have my lines all plugged and ready, is there a trick to bleeding this brake system? do i really need to bench bleed, im using anew 69 booster, and a 69 eldo master. and if anyone is the authority on the 69, am i correct in saying that the brass box im talking about is for sure the proportionvalve for this car or is it just a safety switch.
