Temporarily hooked some wires to the buss bar on the sub panel This is the first step in the harness hanging adventure. These wires are hung according to the wiring drawing. Each wire has an identifying tag label on it.
The switch and breaker wires This end of the harness will be hooked to the switches and breakers after the whole harness has been run throughout the airframe.
First set of wires routed to the firewall The wiring harness has some clipped cable-ties throughout the length of the harness, however there are some cable-ties that haven't been clipped off and are marked with a blue marker. These blue marked cable-ties are cut off as needed to allow groupings of wires to be pulled off the main harness and routed to where they need to go. Here, this grouping of wires goes to the alternator and the magnetos.
Now for the relay wire grouping I mounted some black conduit on the firewall and cut a hole in the conduit about half-way down for the relay wires grouping to poke out and go through the firewall to the relays.
The relay wires Here you can see where the wires go out to the relay switches.
Wires for the relays
Now for the wires that go to the rest of the aircraft Here's a trick that I learned from my dear old Dad. I grabbed a hunk of old wire and taped the ends of the rest of the harness to one end.
Now for some wire pokin' This worked like a charm. The single wire worked it's way passed the pre-existing relay wires and out through the bottom end of the conduit. Now it's time run them wires.
The first run The majority of the wires in the harness run down the center of the middle floor console, except for the wire to the fuel pump.
Now to dispurse the wires Here, I'm routing the wires to the wings and flap motor.
The flap motor wire
The wing wires I'm not sure if I'm supposed to route this wire through the pitot hole or not.
All the wires have been run!
Temporarily installed the ignition switch This switch also comes with 2 other locks for doors and panels like for a Cessna. I may use them on my old C172.
Here's the flip side of the ignition switch Tomorrow I will start connecting wires to the breakers and switches on the panel. I will also have to do crimping of connectors to some wires. I took a class in electronices a year ago when the EAA Sport Air Workshop came to town. The class was great, especially since I don't know squat about electronics. The crimper I bought makes two crimps in the terminal when attached to the wire, which are different from each other. So you need to know how to place the terminal inside the crimper. Here's a video explaining the whole crimping procedure:
