After I got as far as I could on implementing Van's fuel tank service bulletin, I decided that I was going to work on finishing the installation of the HID lamps.

As I did with the right wing, I placed the ballast on the outboard rib for the leading edge.  I centered, and tilted the ballast slightly to accomodate the Yazaki (Harlbera) connector (the connector that plugs into the ballast and connects the ballast to the HID igniter on the lamp).

To hold the ballast in place while I drill the holes for the plate nuts, I broke out the vice grip clamps and locked it down when I was happy with my placement.

A set of transfer punches would have been nice to get the exact center of the hole, but what I did to improve the accuracy of my hole placement is found the drill bit # that just fit in the mounting hole.  I just twisted the drill bit a few times by hand and the center point of the drill bit removed enough material to more or less mark the center of the hole.

Where the center of the drill bit removed the primer, I used a spring loaded center punch to punch the location so that my drill bit wouldn't wander when I went to drill the holes for the plate nuts.

The holes are now marked and centered. 

With the nutplate holes drilled and riveted, I mounted the ballast and everything lined up great.

Routing of the wires to the HID lamp made me scratch my head a little in that I want everything to be nicely routed and look professional.  On the lower left side of the ballast, I drilled a hole and placed a bushing in it where I will pass the wires through the outboard rib.

The one problem I have with this installation is that Duckworks fabricates the wiring harnesses for you.  Well, if the ballast is in close proximity to the lamp, you have an excessive amount of wire harness to figure out what to do with.  As I did on my right wing, I shortened the harness by cutting out a center section and then re-splicing it together.  This is not my first choice of how to handle this, but I looked long and hard for the connectors for this lighting harness and couldn't find them.  I could have probably called Duckworks and bought the connectors if he makes them himself.

Anyway, I measured the length of wire I needed from the ballast to the lamp, cut the wires (offsetting each splice) and reconnected them with butt splices.  I covered the butt splices with a heavy wall shrink tube that has adhesive on the inside.  The adhesive flows while shrinking the tubing and makes a great environmental seal.  After I got the individual splices done, I ran another length of shrink tubing over the entire spliced connections.  This should be at least as good as the original jacketing of the wires.

Point to note here is that I had to run the wiring through the hole in the rib and then splice it together.  I am sure that I will be cussing when I have to replace this wiring.  Probably won't be necessary to replace while I own the airplane.

This is what the routing looks like on the inside of the rib.  I used a nutplate and a cushion clamp to immobilize the wiring slightly and keep it from rubbing / chaffing on the inside of the wing.

A power up check of the newly installed light was SAT.  I can't wait to see how much light these offer during a night flight.  The HID's appear to be extremely bright when running them and shining up the neighbors property.
