This reminds me of when I looked up my trusty Haynes Manual to see how to put my car's electric window back together after it fell apart. Glass simply not connected to mechanism, and winding wire unravelled and off spools/pullies.I cannot see your problem, it's not exactly rocket science to fit Morse/Teleflex single lever controls.
As normal have a good look at whatever your taking apart before you do it or photograph it, or make a sketch.
At the control box end most cables are located in a slot where the sheathed end metal section is secured with a screwed retaining clamp, at the very end of the cable where the screw part is this again locates again in a slot and is usualy secured by a circlip 'and' the end lock nut.
The other end of the cable in the engine bay is even easier, if it is the 'gearbox control cable' it is clamped onto a locater plate from the side of the gearbox,with a small locating clip, BUT, this little clip has a locating grove inside it, make sure you fit it in the right place on the cable sheath section which also has a grove, the screwed end usually needs the nut removed and the round locating pin (usually SS) which connects to the gearbox arm screwed back on from the old cable (if it's ok) and the lock nut for when it is in it's final position.
When I have both ends connected up I put the gearbox lever into 'ahead' and then line up the round locating pin of the cable end to make sure it goes 'all the way', then put the gearbox lever into 'reverse' position and check again the control lever takes it back far enough, if the final position is not enough on either of the above then you need to adjust the locating pins position by turning it on the screwed end.
When all is working ok lock the locating pin into position with the lock nut and DO NOT FORGET, that the Stainless steel round pin that fits the cable to the gearbox lever also usually has a split pin or simular retaining it.
Good luck hope this might help
