First Wiring

Time: 6 hours

I had received a couple packages in the mail a week and a half ago from various vendors. One was from Summit Racing which had the elbow I needed for my smoke tank high pressure hose. This had a male fitting on one side and a swivel female on the other allowing me to hold the perfect angle as I tightened it down. So I installed the elbow and cut the high pressure hose to the correct length. With the hose cut and installed I tightened down the hose clamp and secured the rest of the hose with zip ties.  

   The other deliveries were from Aircraft Spruce, Avery Tools and Dynon.  
 The Avery box had the custom flap push rods that I knew I wanted to get eventually and heard they were retiring and closing shop so I placed the order. All the other stuff was for wiring avionics. Firs up was to run the pre made harnesses for the ADSB and Transponder. I figured out the route in which I wanted to use and ran the bundles. I put the avionics shelves back in place and taped the avionic mockup sin place to start the layouts.  Once I was satisfied with the routes I zip tied and used adel clamps to secure a place.  

    
 I ran the bundles thru various snap bushings and zip ties on their way to the front. I’m not sure to the exact length they will need to be until I solidify the panel and where items will be. So I curled up the remaining length and zip tied them for later work. I used my shrink tube printer to mark the bundles for easy identification later.  

   I installed the bracket I made to hold the EMS box to help with wire length planning.  
 The other Barnes I wanted to run was the network cable from aft area to the from avionics bay. The Dynon system uses this 9 pin d-sub connections to tie each and every component together so they all talk to each other. Each component has multiple connections so that you may tie others into and out of them.  Dynon makes a 5 port hub to allow 4 item to plug in and one out. My plan was to run one line from the two ADAHRS, via a splitter, from the back to a hub in the avionics bay.  Dynon makes these harnesses in various lengths starting at 1.5′ and up to 30′.  So I bought one that gave me enough length to make it up to the avionics area plus a bunch extra that I can use for other runs after cut. Dynon puts a connection on one end and just the pins on the other so you can fish through small openings.  

   I figured out a good spot for one of the 5 port hubs on the forward avionics wall.  
 Last item I worked on was the Hobbs hour meter. I took some advice from my buddy Glenn to install one even though the Dynon system will keep track of it. The reason is that it’s nice to be able to just look at the meter without having to power up the aircraft. This hour meter will be used to mark key maintenance items.  I wasn’t to fond of having this big gauge in the cockpit. While at AirVenture this year I saw another RV that had the meter inside his forward cargo area facing forward. I thought this was great, it isn’t inside the cockpit and it will be easily accessible by opening up the cargo door. So I did some measuring and came up with the spot that’s close to the edge but does not interfere with the door. I used my Dremel tool to cut the opening and drill the holes for the attachment hardware.  

   All this happened last weekend and I was a little behind in blogging about it. I was in Las Vegas for the NBAA convention and had a three day trip right after. Not sure how much time I will get in the hangar this week as its Thanksgiving and we are excited to have family here for the first time in our new home. I have a lot to be thankful for!
