VPX Wiring #2

Today I continued with my wiring extravaganza. I didn’t get any new pictures, but I started by beeping out the ELT DIN connector. I originally made the harness a few years ago, and forgot to write down the wire designations. I tested the connector and verified with the specs provided with the ELT and then made the DSub15 connector for the serial bus. The ELT just has serial Rx, power and ground.

Here’s the DIN connector that plugs into the ELT. The tail sticking out is to test the Rx signal. It will eventually be tucked away.

VPX J10 & J12

Here are two of the main power connectors from the VPX. I connected these and began to separate out the bundles by where the wires needed to route.

VPX J1, J2, J8

On the other side of the VPX are the two D25 connectors J1 and J2. These are for some lower power items, like flap position sensor and interior lights, as well as the VPX serial connection. The J2 connector is for all the switches. These will go directly to the panel switches, which will be connected to ground on the other side.

Bundled by function and aircraft location

These bundles are such that each group will go to the same general area of the plane. The lighting harness for example is split into two half way down in order to go to the left and right, for each wingtip. Others are for powering the aft components such as the ADSB, transponder, and autopilot servos.

Switch bundle and serial bundle

This side contains the switch bundle, which heads off to the right side of the image from my hand, and the other bundles are for the flap position sensor, and the serial connection.

EMS and other wires

Here’s a wider shot showing the EMS in it’s mounting location. Once the plane is built this area will only be accessible by laying under the panel and accessing it from below.

The last thing I did was to drill the copilot’s control stick for the quick release pin.

This pin allows the copilots stick to be removed in case the passenger wants a more comfortable ride. There will be two wires coming out of here for the copilots PTT for the radio. It will be fitted with a connector in order to make the system removable.
