When I picked up my trailer and installed my Andersen coupler, I did NOT install the cable bracket - I carried an assortment of heavy-duty long zip ties and temporarily secured the cable which got me home with no problems. When I left home with this plan little did I know how much I would really appreciate NOT dealing with mounting that bracket on what turned out to be a rather long day
Once home and under no time pressure I looked things over and settled on the arrangement shown in the pics. No holes were drilled in anything, the Andersen bracket is not used - it utilizes existing holes in the pinbox which were fortuitously convenient.
- I removed the "T" handle from the cable end (one screw) along with the retaining nuts on the cable, then just laced it through the holes, adding one additional nut purchased at Lowes to set the 'projection' of the threaded section just right
- Where the cable runs through the pinbox hole opposite the handle I added a short bit of some wire loom wrap I had on hand as a 'wear preventing sleeve' using zip ties (a grommet would be nice but I couldn't source one of the right size conveniently)
- I shot the exposed metal parts of the cable assembly with black Rustoluem I had on hand
In the pic the handle is in the 'unlocked ready to hitch' position, it pushes 'home' and turns to 'lock' just fine, does not come close to the trailer frame. You also see where I zip-tied the breakaway 'switch' wires to the finished assembly.
I have no problem reaching the handle over the driver's side of my truck box (YMMV); If the trailer is at an extreme angle it'll be a bit more of a reach, I'm OK with that. I like that it's all 'high-and-tight' with gentle curves and extremely solid/secure.
An option just for your consideration, Have Fun!
