Down to the wire at Christmas
And while my wife, daughters, and entire family rush to get their last minute Christmas gifts, I use the waiting time to do some last minute re-wires and mini-mods. Picking up from last post of VB Air controller re-wire - finally found my preferred perma location for it - between steering wheel & ignition key. It is the most logical place for me. Since I use/control it 100% of the time while sitting on the driver's seat, then it makes sense to put it as close to steering wheel as I can.
Remove 4 switch blanks. NOTE: The red wire is for Fusion kill-switch, which has to be relocated to the left side of steering wheel.
Drill holes on upper 2 switch blanks and bolt controller holster onto them, use lock nuts behind switch blanks.
Easy snap-on/snap-off for install/removal. 2 top and 1 right bottom switch blanks all back in. The 1 left bottom switch hole is left un-covered to allow coiled cable storage/retrieval. The nice thing about using the switch blanks is I can change my mind later on & un-bolt controller holster and snap-on new undrilled switch blanks.
Disconnect chassis battery via under-dash main disconnect. Un-screw VB Air contoller back/face plate. Un-solder 4 control wires so that coiled cable can route through via the left-lower switch blank hole. Re-solder back all control wires.
Stuff all excess coiled cable back behind switch blank holes. Any need to pull controller outside driver door is easily done by just pulling out the coiled cable. NOTE - it is a lot easier to pull the entire length of coiled cable out than hiding them back in. Hiding them back in requires a 1-finger process done an inch at a time. So may take couple minutes.
Reconnect battery disconnect cable. Assuming no smoke/fire, test operation of all manual & automatic VB Air functions. Perma location done. Much cleaner install, entire coiled cable hidden. My job here is done.
Not a single dangling cable around my dash. 
I can only imagine MB designed it for purpose of additional after-market wire routing. Ugggh! Unplanned work, but once discovered, I had to fix it. Much better now 
I only do it as a labor of love for vehicles I work on, which is probably why AS does not. One has to love it to spend so much time on things that are completely hidden & no one will ever see (except of course me). My wife does not like me taking apart our brand new rv piece-by-piece like this right off the lot but understands my need to do it and it's benefitting her & our family.
