FWF wiring never ends

Mostly been focused on FWF wiring. There are lots of connections to be made and properly securing the wires seems to take considerable time. Fabricating brackets.. etc..

Below you can see the metal L brackets I made along with a short straight metal piece to secure the #2 starter cable to the oil sump. The straight metal piece allowed me to mount the adel clamp for the #2 wire inwards, sort of on top of the sump. The adel clamps down lower allow for the lower voltage signal wires, mainly CHT and EGT, but also throttle position sensor wires to be secured.

I also secured the AC hoses FWF along with putting the ends on the compressor side of the hoses. I secured the hoses to the forward-most intake tube, a plate secured to the left side of the cold air sump.

The hoses connected to the FW and secured (although not in sight) to another metal bracket attached to the bottom of the cold air sump. I may also secure them to the engine mount in the middle of the run shown below.

CHT probes were screwed into their locations in each cylinder. I then got to locating the EGT probes making sure they have clearance seeing they stick straight out of the exhaust pipe. I targeted 2 1/4″ down from the flange. I was able to locate 2 of the 3 on the inside of the pipes and #2 needed to be pointed outside due to the angle of the pipe and the heat muff being on this pipe giving few other options.

I’ve run spark plug wires to their destinations. The left coil pack services the top set of plugs and the right coil pack services the bottom plugs on each cylinder.

At this point the left side is just about complete. Still need to finish the spark plug wires and the Tanis wiring to each cylinder heat element. Time to work on the right side.

Below are some other pics of having a bung welded into the right side exhaust collector for the SDS O2 sensor installation spot. I had a local guy TIG weld this on for me.

I also split the forward tunnel cover into 2 pieces like most builders do with an Aerosport center armrest/console. I also mounted my bracket for the throttle and prop cables.

In unrelated news.. I received my Aveo Engineering Zip Tip wing tip light units. I ordered these at Oshkosh, so 6-8 weeks turned into 6 months wait time, but they are here and they look great!

Zip Tips!
