Wire runs

[PapuaPilot]

I avoided going down the middle bottom of the plane to avoid the fuel lines, flap and elevator controls. Starting from the backside of the panel most of my wiring goes to the right, down to the floor and aft under the doors. Then the wing wires go up the rear door post and into the wing spars. The left wing wiring goes to the left side of the panel and followed a similar route. I made channels to hold the wing wiring that I mounted to the front of the aft triangle windows, I didn't want to run the wing wires on the angle tube along with the fuel hoses.

I also chose not to put plugs at the wing root as it can readily be disconnected at the wingtips and pulled out. I used the black plastic sheathing inside the spars and in any other area where protections from rubbing could occur.

My wiring runs thru the center between the seats in some aluminum angles and light plastic conduit. Used Weatherseal connectors at the wing roots and at the tips. The plastic header tank was replaced with aluminum shortly after photo was taken.

I used the same connectors for my wing lights as you did, Jim... at the wingtips & behind the seats. Ran my wires through 3/8” black thin-wall sprinkler system tubing through the spars. Running your fuel line towards the center takes 1 or 2 less bends than going around the right side like I did, which is good. I made an aluminum channel for a wire chase located under the pilots seat, and ran another bundle under the right seat supported by Adel clamps and the airframe tubing, transitioning to a couple more channels under the center counsel going up to the firewall area.

Thanks, guys,
It is always amazing to me how many wires we need for simple planes!

I've done the same routing as Phil; i.e. rear fuselage wire cables down the RH side and wing cables down the LH and RH sides. I've reserved the centre console area for fuel and brake lines only, rudder cables excepted of course .... Separates electrons from fluids.

Separating wiring from fuel lines-I've always wondered why this seems to be a big deal. What are the odds you will have a fuel leak at the same place and exact time that the wiring shorts out and causes a spark? Seems pretty remote to me. Only in a bad crash might these odds come together. I'm not saying its a bad idea, just personally would not go to too much effort to keep them separated.

In my centre console, the shut off valve is the only union. My fuel pumps are on the other side of the wall so if I had a leaky hose it would suck air not squirt fuel. I do try to keep them as separate as practical but if they are a few inches from each other I’m not worried
