As I have all the parts, I decide to fabricate the Pmag ignition harness.
On the ignition side, the cable has first to be inserted in the angles rubber boot.



Then the cable has to be carefully stripped and the pin crimped. The crimper was included with all the parts.



Then the pin is bent at 90° and the boot is pushed over the pin.



For the plug side it's easier. First strip the cable 1/4".



Then install the small spring, the nut, the silicon gland and the washer.



And a check for continuity as the cable core is easy to break. The resistance is shoube around 180 Ohms per foot, as the cable is 2'5" it looks good.



I the install various elements on the engine, more to have an idea how to organize everything and check I have all the needed hardware.
This is the oil pressure hose going from the engine to the manifold to be installed on the firewall.



I the install seals for the upper plugs ignition wires, the holes seem a bit too small, I'll have to enlarge them slightly.



I the bolt the oil cooler to the firewall, only to notice that the fittings' orientation interferes with the engine mount.

I begin by installing the rear baffle that has to be drilled for the fuel hose going from the injection block to the injection spider.
The picture shows the result.



Then I installed some clamps to hold the ignition cables for the lower plugs.



I then wanted to fabricate the harness for the electronic ignition, but the parts I had did not match those in the installation manual. I took this picture to sort this out with Mattituck or Emagair.
Even if the parts are correct I'm missing one of the silicon glands.



A visit to the EMagair website showed that the installation manual has been updated and that my parts are correct. I now have to find one of those silicone glands.

This is the second try to cut the foam n=block in the sccop. It worked and this time I left the cowl on the plane to do the sanding. This way the air filter box could be used as a guide.



I then laid the first layer of fiberglass. Vans method of using a balloon to maintain the fiberglass did not work as it created a scoop that did not match the airfilter box inlet shape.
Once cured I will lay a few other layers.



I also modified the gascolator so that the drain plug can be operated without removing the lower cowl.

The foam block being glued to the scoop, it's time to make the cut. Here, the begining.



And now the cut is finished. The picture shows the the foam doens not extend completely to the airbox. This is not really a problem.
A run into trouble when I began sanding the foam as it is very fragile. I wasn't carefull enough and am not satisfied with the result. So I glued another foam block and am back to square one.

I received the hose i needed to complete the exhaust hanging. After having checked all the gaps I used some black electrical tape to mark the position of the clamps.
