I'm just starting to run conduit for fuselage, wondering how many 7/8 sections are necessary for tailcone area.  I currently have 3.  The ones I'm planning for are:



1)  Static tubing?

2)  Battery positive

3)  Battery negative?

4)  Rear Light

5)  AHARS 

6)  Pitch servo

7)  Elevator Trim servo

8     O/H console air controller

9)  O/H console lighting?

10) ELT



Is there something else I should be planning for?

I actually wouldn't use any conduit in the tailcone itself, and

wouldn't use any conduit in the sidewalls by the pilot/co-pilot

seats.  The only place I'd use conduit from the area on the

side where the rear passengers feet are, to where it exits

into the tailcone.



Your best bet on the wiring/conduit sizing for that job

then is to cut a few 6" pieces of wire for everything

that you plan to run into the tail, and just bundle it up

and see what sizes of conduit you need....but probably

buy at least 150-200% more space than you need, because

you'll surely forget some small wires or want to add them

later.



I have 2 conduits of 1.05" each, and they're pretty darn full.



Oh, and to add to your list:



10) ELT control wire

11) ELT GPS wire perhaps

12) Nav Antenna coax

13) GPS antenna coax

13) Power/Serial wires for APRS perhaps

14) TCAS/ADS-B system wiring and possibly antenna coax



and the list goes on and on.

What you install now, will probably not be the end of what

you eventually have.

On Mine:



LH side: #2 ga power to front, 14ga power to strobe power supply, 2 ea 16-3/S strobe cables to wings, 18 ga  tail pos light, pitot tubing to grt ahrs.



RH side/Bundle #1(only one in conduit): Elt phone cable, dynon magnetometer 4-22/S, GRT ahrs/magnetometer harness, spare 18-3S, 10ga aux bat e-bus feed, 16 ga aux bat hot feed to front, crossfeed contactor and e-bus relay 22 ga grounds. 



RH side/Bundle #2:  VOR RG-400, static tubing to front, 2 ea spare 18-3/S(for ads-b down the road or anything else in the tail), pitch ap servo harness, pitch trim 5-26/S cable.  



I only ran one conduit, the other two assemblies I did before covering the area. I only use conduit for wiring that I did not have or know about at the time. Everything that I could think of at the time got ran inside bushings, rubber grommets, ms clamps. I just like have my wires tight and not flopping around loose inside the conduit. Same for the wings. I run wires for hvac inside conduit on fixed equipment. Over time vibrations in the plane may or may not be good for the insulation. Conduit holds the heat in the bundle longer. I did not see the point in using high dollar tefzel wiring then enclose it in highly flammable plastic. I am sure there is a MS type conduit, but I doubt Van's supplies that. 



So if going with conduit and running a ground up front 3 should be fine unless your installing spares like I did then you may need 4. 



Been working on cabin cover then alternating with some wiring while epoxy cures. About ready to paint the interior, install some led lights/rg-400 to top com and install it in a few days. Doors after that...oh boy.

ground to frame? saves weight,cost and space

On a new aircraft, grounding to the frame works just fine.  However, in 

the presence of an electrolyte ..... I live near the coast of FL .... 

salty air ..... I believe that current flow will hasten corrosion in the 

structure causing 'gremlin' problems down the road.  I'm installing the 

ground cable up to the firewall and to a ground block.  All my smaller 

wire ground returns will connect to that ground block.  I'll probably 

not live long enough for problems to occur in my -10, but it's possible.

Like others, I took the approach of running everything I could plan 

using clamps, grommets, etc.  Then I  have 2 runs of conduit, just under 

the rear floor section that Tim described, for the 'unplanned' stuff.  

The planned stuff is mainly big wire electrical system stuff.  The 

unplanned is more avionics and small circuts.  Stactic lines I ran on 

the rh side wall.



I'd suggest getting the documentation for Van's electrical kit.  It has 

details for running a lot of electrical system wires including 

clamp/grommet hardware for running stuff from back to front.  (There's 

good stuff for FWF wiring too).  I wouldn't suggest the kit itself, just 

the doc.



Then  just add some empty conduit for other stuff.



Added a pic of battery compartment to show some of big wire electrical 

system stuff at the bottom, and a conduit run in the middle of the pic.  

You can also see my battery to frame ground setup.

This is what I did also,,,,,ground cable and terminal block at the firewall..  FWIW, I ran two 1" and one 3/4" conduit (the flexible kind from Home Depot) snaked through the baggage rib lightening holes, edges protected with edge grommet, on each side (total of 6).  They come up through the rear seat pans between the side covers and side fuselage skins.  My SafeAir static/pitot lines are on the co-pilot side and run through snap bushings installed in the bulkheads.  I am using heavy #1 marine cable, positive and negative, each in its own conduit.  Two more of the conduits are used for two antenna coax cables, and several bundles of other wires for elevator trim, rudder trim, strobe cables and power supply, rudder position light, elevator AP servo,,,,etc.  Bottom line is I have two leftover 1"conduits for future wire runs I haven't thought of, or might need down the line.  Run them now before you rivet the floor and seat pans down.  You  will not be sorry if you have one or two unused conduits but will be if you find out later you need one but did not put one in while you could.

Wanted to add that you can use the doc and a parts list to identify any 

small brackets or stuff that you may want to order a la carte.  Worked 

well for me.

Where can you get the vans’s electrical kit documentation? Will they give it to you?

Search for DOC ES HARNESS-10 540 at Van's web store. It costs 10 bucks.
