Super Slick Dynamo Wiring on my RB-T

I've recently completed the wiring of a Luxos headlight and taillight on my Bridgestone RB-T. Because this is the most extensive and fastidious wiring I've done on a bicycle yet, I figured it would be worthwhile to share my experiences.

I'm using a Schmidt SON hub mated to a Mavic A319.  I've got Schwalbe Marathon Supreme 700x35c tires F&R. I'm using VO Zeppelin aluminum fenders. 

I ran the wire from the hub to the fender along the right fender stay, using zip-ties to keep the wire in place. 

This is also a really clean route for the wire, as it is barely visible. 

Because I have enough extra room between the fender and the tire, I chose to run the wire on the underside of the fender. Elton at Harris Cyclery told me about a method he learned from Somervillian, whereby you use HVAC duct tape (the REAL stuff, made from aluminum with adhesive on one side). 

The adhesive sticks like crazy, and if you are using silver fenders, the tape completely blends in with the metal.  Also, because this tape is meant to take high heat, it should last a long time. 

In the front, I used a rubber grommet to bring the wire up through the fender beneath the fork crown to connect back to the taillight wire. 

I then ran the wire along the downtube, using zip-ties to hold the wire.  I then ran the wire beneath the bottom bracket and through the hole in the rear fender. 

I then ran the wire up the inside of the rear fender to the taillight, at which point I drilled a hole for the wires to exit and connect to the light. 

Because I'm using a Luxos U, there is a third wire to worry about: that which connects to the cache battery and the associated USB port for charging my phone while riding. I have not found a very elegant solution for this, so I run the wire from the headlight, wrap it around the VO rando rack and then up to the stem where I've mounted the switch/hub. 

Lastly, because I've recently purchased a Rivendell Trunksack (small) for my rando rack, I needed to be able to mount the front light in a place other than at the fork crown. Harris recently started carrying the M.A.P. Cycles front light fender mount. This was exactly what I needed, BUT the Luxos Is really deep, so it interfered with the rando rack when mounted at the very front of the fender. I took some aluminum bar stock and made an extension off the front of the fender into which I was able to screw the light mount. EDIT:{The aluminum bar stock wound up failing due to metal fatigue from bouncing up and down after only a few rides. Fortunately the light did not roll of a mountain when the piece broke, but I certainly learned my lesson. It has since been replaced with an extra steel rack strut that I had.  I cut it to length and put it in the same place on the underside of the fender. The light mount attaches to that in the same manner. It's been rock solid ever since.}

Hi. Where did you find the rubber gromlets?

I just went to the hardware store and looked in the area where they keep all the screws and small bits. I bought a few different sizes as I wasn’t sure exactly what I was going to need, and they are cheap (about $0.25 if I recall correctly). If you ask an employee at the store they should be able to point you in the right direction.
