Completed the Wiring - For Now







During past few days I completed all of the wiring with the exception of a few items where I am awaiting a reply from Van's support. Then re-installed the rudder pedals, hopefully for the last time.

Bundling of the wires and then routing them so there would be adequate clearance for the rudder pedals took some time. The two DG6 clamps have to first be flattened a bit so they are not too thick as they will interfere with the rudder pedal torque tubes. The plans show the clamps pointing inward. This will not work because there will not be enough room for the rudder pedal blocks to slip in between the two clamps. Van's support indicated it was acceptable to point them outward. Trying to fit all of the wiring, the two coaxial cables and the static line thru two clamps is nearly impossible without crushing something. A better solution would have been to use two smaller clamps pointing inward and the two flattened DG6 clamps pointing outward.

Inserted the rudder pedals. Bundled all of the wiring above and below the panel. Installed the autopilot disconnect switch in the central panel section and wired it to the DB-37 pin connector. Inserted the pins from the music wire harness, the PTT wires and the trim wires. Attached the hood.

Was ready to complete the DB-25 pin connectors but ran into a problem. Page 31-07, Step 7. Looking at the MAIN DB-25 pin connector on the WH-RV12-OPTIONAL harness. There is a white-black wire and a orange wire with female pins attached that are NOT inserted in the DB-25 connector. The wires are just hanging. Jim Cone saw the same.

Traced the wires and they are a part of the future autopilot servo harness. There is an orange and a white black wire in this 7 wire AUTOPILOT SERVO harness. Page 31-09, Step 8. Checked with a DVM and there is continuity. The same wires continue to the tail.

So they most likely SHOULD be inserted into a location on the MAIN DB-25. Will await an answer from Van's support.

So, with regard to the wiring, the DB-25 connectors need to be completed and the magnetic reed switches need to be installed. I am awaiting a response on both of these items.

Also need to attach the fittings to the static line (will wait for the Dynon D-180).

Time over Past Few Days - 8 hours
