I got home and the light was por so I just snapped this one photo. It is a bad picture but I think you can see from it what I'm going to explain.
On each frame rail in front of the front leaf spring eye hanger is a bracket. The short cables comming from your rear drums are held in the brackets with clips. On both sides there is a suare connector bent in the shape of a U with a keyhole in each end. The ends of the cable from the rear go in one end and the end of another cable (without a housing) go in the other end. All it does is link the two cables. Now the one without a housing forms a huge U. One end at each of the rear frame brackets connsected to the rear cables. At the front one corner of the U (passenger side) has a fixed rod comming from the frame with a short housing piece the cable rides in. On the other side is the same thing but instead of just hooking to the frame the housing is connected to the cable that attaches to your e-brake pedal. Here is another low light crappy picture of the front cable on the drivers side attaching to the corner of the big "U"
When you depress the e-brake pedal the cable pulls on the one corner of the giant U of unhoused cable and thus pulls at both ends in turn actuating the e-brake in each side of the rear end. I'll look in my Fairlane shop manual and see if there is a diagram of the cable system I can scan.
