Fuselage Wiring

Today I did a lot of wire organizing in the forward section of the fuselage, under the panel. All of the cables routed from the aft fuselage and under the seats funnels into the center section and routes on the floor up to the panel.

Once I organized the rats nest of wires I ended up with two nice bundles. These include the two trim motors, flap motor, ADSB, transponder, ELT, and ADHARS unit. These will be wired to the different serial and power connectors under the panel.

On the right side of the fuse I’ve separated out the radio antenna wire so that I reduce interference as much as possible. This will be behind there side panel from my interior, so it won’t be seen. The RG400 coax wire has a minimum bend radius of 1in, which I am well above in all these bends.

On the left side of the fuse I’ve bundled my two autopilot harnesses. These are separated out from the power wires and autopilot disconnect which will route directly to the pilots stick. The Dynon autopilot harnesses are the standard SkyView Net 9 conductor harnesses except for power. So the only wires needed are the paired data wires.

Here are the Dsub15 connectors for the GPS, ADSB, and Transponder. The red wire for the ADSB and Transponder are left off the connector in order to connect to the VPX. The GPS is powered by the SkyView screens, so it’s fully pinned into the connector.

There are 5 components that use serial connections. In order to connect all the serial to both the PFD and MFD screens, I made a serial bus board that has 7 connections. These are all hooked up in parallel on each pin. When I connect all the connections to the board, each screen will be hooked up to each component properly. I’ve done the pins so that each Rx and Tx from the screens are assigned properly.
