I opened the new SkyView Display Harness and installed the panel mount USB cable.

While looking at the wiring diagram for the transponder, I noticed that there were a couple of loopbacks, so I installed these using some 22AWG wire.

I also got an order from Van’s that included this pressure switch.  I installed it in the right port of the manifold using an AN915-1 elbow.  This will drive both the hobbs meter (connected to the NO pin) as well as one of the annunciator lights to indicate low oil pressure.

I went ahead and installed a wire to the ground pin.  Since I don’t have a ground block on the firewall side, I ran this through the pass through so I can connect it to the ground block on the cabin side.

I decided to go ahead and label the ground wires.  The labels are facing downward since I’ll only be able to see this from below once the last skin goes on.

I have no idea why I didn’t think of this before.  Since I have a label maker that will print on heat shrink tubing, I printed up some labels for my drill bits.  Trying to read these numbers on the bits themselves has become quite a pain.  You can also see that I put the screw/bolt size on the label as well so I don’t have to look these up on a drill guide.

I installed the ARINC-429 module on the front side of the subpanel on the pilot’s side.

I installed the backup battery for the left display on the back side of the subpanel.  Batteries have to be replaced from time to time, so I wanted these to be fairly easy to access.  With the tipup canopy open, these are easily accessible.

I also put a new terminal on the battery positive cable with a 12AWG wire for the battery bus.

I also installed a couple of adel clamps to tie the battery positive cable to the engine mount.  Without this, the terminals would have to carry all of the weight of this cable (and it can weight quite a bit when I’m pulling 6Gs).

The battery bus cable comes through the pass-through and will connect to the battery bus via the bolt on the bottom.

The Dynon transponder uses a TNC connector instead of an BNC connector.  Fortunately, Fry’s carries RG-58 TNC crimp on connectors.  I’m using RG-400 which uses the same connectors.  I crimped it on to the end of a piece of RG-400.  I’ll cut it to length and put a BNC connector on the other end to connect to the antenna.

I was originally thinking I’d install the transponder and antenna under the passenger seat, but Dynon recommends at least 3′ of separation between the transponder and COM antennas.  Instead, I decided to mount the transponder behind the baggage wall underneath the pitch servo.  The transponder clips to a mounting bracket that is screwed to the center rib just in front of the shelf where I’ll mount the ELT.

Now that the EMS is in its final position, I cut the oil and fuel pressure lines and added crimp ring terminals.

I also crimped the connectors on the manifold pressure sensor wires and installed it in the MAP sensor.

Lastly, I installed the sensor wire on the oil temperature sensor.

I played around with routing the shunt and fuel flow sensor wires over to the right side of the engine.  I decided to have them follow the Light Speed ignition sensor wire to where it mates up with the starter wire, then turn and follow that across the engine compartment.

Here you can see those wires follow the starter cable over to the connector.

They then jump over to the alternator feed wire.  The shunt wires separate there and will connect to the shunt just behind the left tube here.  The fuel flow wires follow the alternator feed wire forward to where the fuel flow sensor will be mounted.

I got my transponder from Dynon.  I purchased the high-power, class 1 SV-XPNDR-261.  This thing is nice and tiny, but still puts out 250W of transmit power.  It also meets the full ADS-B out requirement when connected to a TSO-C146A GPS (such as the Garmin GTN series that I’m going with).  It also displays TIS traffic on the SkyView which is handy around the areas I fly in.

I also received the ARINC-429 module.  This lets the SkyView interface fully with the Garmin GTN unit to get features like GPS steering for the autopilot, CDI autoscaling, and vertical guidance for approaches.

I also purchased a second SkyView Display Harness.  I decided to purchase this separately so I can hold off on purchasing the second display until just before flight.  I can move my single display between sides on the panel when building the overall harness.  You can also see that I purchased a second panel mount USB cable.

I also received a second battery for the right display.  I can go ahead and mount this and connect it to the right display harness.

I also picked up two 30′ network cables.  I’ll cut these up to the custom lengths I need when connecting components.

I also picked up a hobbs meter from Aircraft Spruce.  Although the SkyView has a hobbs built in, I don’t like the idea of having the only record of aircraft flight time being stored electronically.  If there is a failure or I have to send a display back for service, there is always the possibility that the total flight time is lost.
