Jim, the cable terminates in an adjustment bolt that simply extends through the frame of the trailer in front of the street side tires. You will see four bolts there, one for each cable. You will see them if you get down to the tire level and look for them from the outside. They are held in place by two nuts, the outer nut is a locknut. You will loosen that one first to make any kind of adjustment to that cable. You will probably have to hold the bolt on the inside of the frame (under the trailer) to turn any of the nuts.
Locate the cable you are planning to reattach, unscrew the lo cknut on that bolt (I'd just take it off but put it in some safe place). Then, unscrew the second nut to the end of the bolt and see if that gives you enough slack to reattach the cable to the top. If not, take the nut all the way off and that will free the cable.
Once you have the cable attached, you should be able to reinsert the bolt into the frame and attach a nut if you had to take it out. Make sure the cable is still on all the pulleys. Tighten the nut till the cable slack is removed and the cable feels as rigid as the others. Put the locknut on and tighten it down. You will NOT have to adjust the other cables if they were ok before.
Check that the bulb seal on the top meets the lip on the lower half when you raise the top. If it does, you're done. Tighten the cable more to raise that section, loosen it to lower. You want the bulb seal to JUST meet the lip, and not be deformed.
