Hi all,

I'm about to finalise my wiring between the wings and panel. I have opted for qick disconnects at the wing root and plan separate molex connectors for the DC wiring and strobes, BNC bulkhead connectors for the Nav and MB antennas and bulkhead connector for the pitot. The plans suggest that a single hole be enlarged to accommodate the wiring to the wing. Before I make swiss cheese of the fuse (ie 5 holes per side), would appreciate feedback on what others have done and whether Vans has limitations on the number, size and location of these holes.

cheers,
Ron

That is exactly like I did. About 4 – 6 inches behind the spare I have a hole drilled for a 14 pin CPC connector for general wires, then I have a 4 pin CPC for the Strobe Wire (Ensure to connect the shield to one of the pins) and then I have the bulkhead BNC for my NAV/GS Antenna. My Marker Beacon Ant is in the Tail cone.

Here is how I pinned out my CPC 14 connectors in each wing.



Pin   Left Wing Disconnect   Right Wing Disconnect
----------------------------------------------------------------------------------------------------
1   Taxi Light Power   Landing Light Power
2   Nav Light Power   Nav Light Power
3   Pitot Heat Power   N/C
4   N/C     N/C
5   N/C     N/C
6   N/C     N/C
7   N/C     N/C
8   N/C     Autopilot Roll Servo – DB9 Pin 9 - Gnd
9   N/C     Autopilot Roll Servo – DB9 Pin 1 - Power
10   Ailron Trim Motor   Autopilot Roll Servo – DB9 Pin 2
11   Ailron Trim Motor   Autopilot Roll Servo – DB9 Pin 3
12   Ailron Trim Blue Wire Autopilot Roll Servo – DB9 Pin 4
13   Ailron Trim Orange Wire   Autopilot Roll Servo – DB9 Pin 5
14   Ailron Trim Green Wire   Autopilot Roll Servo – DB9 Pin 6


Now I have moved my OAT to the Left Wing so I will need two more of the ones that are now N/C (No Connection) and use them for the OAT Probe. This is the main reason I used the CPC-14 connector was to have extra pins for future growth.




Thank You

Ron,

I put my CPC connectors on the wing inboard ribs - inserted a plate in the lightening hole. I did not put any connectors on the fuse side. I used a separate Molex for the strobe and located it well behind the other wires.

The scientific way to make this decision would be to measure the RF field around all wires and decide whether there was any risk in bundling them. But most everybody just uses one rule of thumb (ie., heuristic) or another.

Mine goes like this:
Strobes and lights can go together, along with other high current lines (e.g., pitot heat). Shielded (RG58, RG400) antenna lines want to be some distance from high current lines -- at least a few inches if possible. And unshielded low current lines like magnetometer wires headed out to the end of a wingtip want to be about as far from high voltage pulsing lines as possible.

This added up to 3 or 4 holes each side.
