Have seen a few different ways that people do the chains/cable from their rearend to the humps. Straight up and down, looped around top of the hump From rearend to back side/bottom of hump straight From rearend to opposite side frame rail at the back side/bottom of hump
What way do you guys do it and have any specific reason why?
With a coiled car, chaining the hump to the rear end doesn't add a lot. For any leafed car, chaining the hump is helpful to keep the hump from buckling. The specifics of cable, outside/inside probably doesn't mean much. More important is that it's beefy enough to withstand the force.
Just be sure nothing sharp is near the tire as to not cut it. It would be best if you include the body as part of attachment just to add another contact site between the frame and body.

Coils I go around rearend housing and through spring and up through the spring bucket and back to the chain through the center inside spring. Gms I run chain center of hump to hump with a bolt with washers von both sides then the chain on the bolt and pull tight. ( this being since a hump on Gm will collapse easier I use bolt to pin it. Then on ford's I run chain up through the trunk through each rail just at bottom of the arch close to trunk all threads since they ford's can move right there side to side to keep out of tires and I run it through trunk to keep from being hung up on any one. Only coils I will not go around the hump or frame because it will turn the rail side ways which then it's weaker at that angle.

I welded a nut to top of rear and used 9 wire around the hump so its straight up and down and was able to get tighter then chain. Hoping with homemade shocks pushing up and wire pulling down it'll help

Careful it will kink and break sometimes from moving up and down some. unless you have super stiff springs in the rear and have everything as tight as it can go... I have bad luck with wire. Maybe now that you have it tight wrap chain around with a long bolt or threaded rod strecthed out as far as you can to get nut on and impact it down even tigher... JMO
Depends on vehicles, but your major coil cars I usually weld threaded rod to set height (id rather keep that then chain but some rules dont allow it, as long as its not through sheetmetal I dont get why that is) then if it has to be chained I will usually go up around the package tray and through the spring and suck it tight to keep height there, then remove rod. Try to keep the height where I want it while also trying to hold the spring in.
But, there are different ways for different cars. Leaf spring I always run a little different and try to get something on the outside of frame to prevent humps from blowing outwards. I guess if you had that issue on coil you could do similair.
