Been on the road a fair amount over the past few weeks including a little vacation in Sri Lanka which was great but had me dropping out of my own thread pretty much right after posting about the receiver hitch for the most part but Unseenone is really the expert with it so his input was most welcome.
Sri Lanka, if anyone is wondering, is a fantastic place to go play. They also have the strong British heritage so there are a fair amount of Defenders on the roads as well as newer Rovers; i.e. D3 & D4s (all RHD, and mostly diesel).

The Islamic New Year gave me the opportunity to catch up on a few odds & ends and I figure I may as well post some reflections as things stand now for the sake of posterity.
-
Coil Conversion : Remains solid and I am very happy with the end state as it relates to the truck's handling. I'd tried to wire the black (orange) box via the instructions that AB provided but it caused massive transmission ECU issues so I buttoned it all back up and started a dialogue with their tech. They sent me a new box, I re-attacked and still had issues. That said I did re-flash the ECU the normal way & at the same time pulled the air suspension fuses (F3E, F26E, & F35P) and what I'm left with is the red suspension light on the dash but no scrolling messages (what had annoyed me the most) nor even 'suspension fault' warnings. The absence of warnings and dinging/donging warnings is good enough for now-I'll try again in the U.S. perhaps. (no pics, though I have plenty from the dialogue with AB if anyone is interested about snipping wires on your suspension ECU and such).

Hitch setup: Decided I wanted to see what it would look like as a rear recovery point so I grabbed a 2" receiver shackle bracket, drilled a hole to get it flusher to the hitch itself, and upon being satisfied with the end result threw the setup into the recovery pelican case. I also grabbed some bicycle tire patches and placed those over the inboard parking sensors since they were losing their mind. All is well now-both aspects can be seen here:

Headlight/foglight switch debacle cleanup : Sometimes I wonder if I don't do things the hard way if I do them at all. In wiring an aux switch in the panel of the headlight switch to control the 4k's on the bumper I manage to hit something in the switch itself and thus I lost my instrument cluster lights...figuring this was my penance for being dumb, I ordered a new switch from eBay. I didn't look close enough and ended up with an LR3/RRS switch that didn't have all the functionality my previous switch did (i.e. foglights & such). Ok, it got the interior lights back on. Today I went by my favorite local Range Rover salvage yard and bought yet another switch, which I promptly mangled too b/c I am dumb.

That said, learning occurred. What I found was that the aforementioned different switch part #'s share the same control board-thus my one working switch could be combined with my other switch components and ultimately by the end of the day I had my original switch functionality back...like I said, I is dumb. This board is the one that can easily be damaged if you leave the switch assembled while modifying, if you look carefully the small circuit on the upper right has one electrical prong snapped from careless application of a drill bit through the plastic housing.

The lesson I learned in retrospect would be to take apart the switch in full (the face comes off, then the area behind the face can further unclip from the electrical portion behind it.) It is this middle area where plastic must be trimmed away to make room for an aux switch's wiring as well as to give a path out of the switch body to connect to the wiring running to the relay and such. The one on the left illustrates what I ended up with, the one on the right is my clumsy disastrous first effort. Let others not follow suit unwarned!

This is the end result, if but for no other reason than to provide closure to my own private debacle.
