Ok so I finally got it the night before last and let me start by saying: this has been a PITA and a SOB and I've on occasion wanted to sit down and cry, BUT having done it it is definitely the most satisfying job I've done on my bike and the difference in light output is INSANE!
The main reason I had such a time of it was that without clear instructions it was experimenting and trial and error most of the time despite having read (and reread) the massive amount of info on this and other forums. So what follows is an attempt at an overview of the pitfalls where I got myself into trouble and some of the photos that I would have liked to have available to me. Hope it helps someone out there, because this is a mod so well worth doing despite the pain
Starting point: 2005 FZ6 with BD43's dual headlight mod, Morimoto mini H1s, H7 harness, H4+H7 adapterplates, Mini Graphite shrouds
First steps: Taking apart the front fairing and baking the headlights were pretty painless. Likewise priming and painting the reflectors - I went with mat black. (Although having never taken my fairing apart before it took some time and REMEMBER to mark those screws!!)
Problem - Cutting & Fitting Shrouds: The shrouds are too big for the reflectors. I'd read that you had to cut them, but I hadn't found pics of how or how much. At first I thought the right angles on the inside of the shroud had to line up with the corners of the projector - THEY DON'T.
Hence the first shroud I cut (pic 1) ended up being cut ugly and too much, but the corner in question is covered completely by the headlight housing front.
I tried different techniques for cutting the shroud including heat, pliers and knives. The best was definitely pliers and a file (pic 2).
Shroud no. 2 was cut much more nicely and less (pic 3). Be aware that most likely the shrouds need to be cut slightly differently.
Problem - Mounting the Angel Eyes: Reading on the TRS site it seemed they were mostly mounting their angel eyes on the outside of the shrouds, but they fit nicely inside the graphites I had. I was slightly confused by the shroud centric rings and whether or not these were required, so I emailed TRS and they said:
"We use the CCFL rings, a few dabs of silicone, and then the centric rings in behind them."
So that's what I did. Had to file a groove in the shroud centric rings to allow passage of the wires for the angel eyes (pic 4) but other than that it was pretty straight forward once you knew the deal (pic 5).
Tip - Test Test Test: Keep a standard 9V battery handy for testing both angel eye and solenoid (the plate in the projector that switches hi/lo beam) function (pic 6). Obviously the angel eyes won't light up to full power with this, but you can make sure you haven't destroyed anything.
Problem - Where do the orange bits go? Embarrassingly I had to ask that in a previous post here (thanks Zargof for sorting that out). Here's a pic to eliminate any remaining doubt (pic 7).
Problem - Wiring!!! Calm down, it's really really going to be fine!! This is what I had to work with (pic 8). The two major issues I had were
a) How to wire the angel eyes to the bike lights?
Well, I went with wiring them to the running lights (pod lights - my bike is European and was thus born with podlights). Black wire is ground and blue wire (or blue with green tracer) is live. I hadn't soldered anything in anger for 10 years, but I went ahead and stripped the insulation off the wires on the bike harness and soldered the wires for the ccfl power supplies on there (pic 9 - not the best soldering in the world but it works).
b) The spades on the bike male connectors don't line up with the harness female connectors (pic 10).
Ok this is where it gets a little interesting. TRS recommend that the wiring harness you get has connectors corresponding to the lo beam bulb on your bike - in our case H7. Fair enough. However Yamaha in their infinite wisdom uses only H4 connectors on the bike's harness (at least for my model and year) and the H7 bulb is fitted with an H4 adapter. So effectively both our hi and lo beam bulbs are H4 connected factory standard. Which is why the spades don't line up.
I haven't seen an H4 harness and can't comment on them. BUT I would suggest you check your connects and talk to TRS before ordering at the very least and I THINK that ppl with bikes of my year (05) should be ordering H4 harnesses.
Anyway what I did was go to an autoparts store and get some H7 male connectors. Note that H4 has three spades Hi, Lo and Ground, while H7 has only two and run both Hi and Lo off one spade. After some research online I figured out that the original bike wire harness had one "Hi beam wire" (BLACK with YELLOW tracer) and one "Lo beam wire" (BLACK with GREEN tracer), i.e. one signal that turns the lights on and and one that is only live when the hi beam switch is flipped.
After rewiring that means you have a hi and a lo beam H7 connector, which fits right into the way the TRS wire harness is set up (it splits each hi and lo beam input off into two) and suddenly presto - no need for the BD43s headlight mod anymore!
