Vans Aircraft RV-12 Airplane Build, Section 42D: Skyview Update (part 5)

Reference: Pages 42D-22, 42D-23; 2.75 hours

This entry will complete most of the wiring update for the Dynon Skyview EFIS in the RV12 airplane. At least the fuselage wiring. The second half of this entry shift focus to the wing wiring connectors on the RV12 aircraft.

Step 1: Find the WH-350 (WHT) Power Outlet Wire coming from the WH-00026 RV-12 Option Conversion Harness previously routed through the F-1203A Bulkhead. Strip the routed end of the wire and crimp on a spade connector. Tie-Wrap the WH-P350 to itself as shown on page 42D-22 of the RV12 airplane plans.



Step 2: (NA ) Using page 31-10 and Section 45 as a guide remove the WH-B148 power outlet wire.

Builder's note: I never installed this wire as I had already planned to go to the Skyview EFIS system.

Step 3: The WH-P440 (ORN/BLK Audio Power wire coming from the WH-00026 RV-12 Option Conversion Harness splits near the F-1203A Bulkhead into the shorter WH-P600 (ORN/BLK) wire and longer WH-601 (ORN/BLK) wire. The split in the wire needs to be located between the F-1202F Bulkhead and the F-1203A Bulkhead. Route the longer wire to teh right side of the Fuselage through the snap bushings in the Seat ribs. Route the shorter wire to the left side opening. Cover the ends of each wire with heat shrink then tie-wrap them to the headset jacks. See page 31-10.



This completes page 42D-22.

Reference: page 42D-23

Builder's note: This page in the instructions says this page is intended for builders who have completed the steps marked D-180 in Section 31A ... It is true steps 1 and 2 didn't apply but step 3 was important!

Step 3: Find the WH-L439 (YEL/RED) But mine was white!!! Nav Power Wire coming from the WH-00026 RV-12 Option Conversion Harness previously routed.

The nav power wire splits mear the F-1203A bulkhead into the shorter WH-L456(YEL/RED) (This wire was WHITE also!!!) and longer WH-L458 (YEL/RED) (Actually WHITE) wire. The split in the wire needs to be located between the F-1202F Bulkhead and the F-1203A Bulkhead.

Route the longer wire to the right side Fuselage Side Cover opening through the snap bushings in the Seat ribs. Route the shorter wire to the left side opening. Crimp a ES-00079 Floating Connector Pin 16-20 AWG on the end of each wire then insert them into position 6 on the floating 8 position connectors.



This completes page 42D-23. Now the focus of the wiring shifts to installing the new wing wring connectors. This is covered in Section 31A and is the other entry for the day.

Vans Aircraft RV-12 Airplane Build, Section 42D: Skyview Update (part 4)

Reference: Pages 42D-20, 42D-21; 2.5 hours

Steps 5 & 6 on page 42D-20 are the only steps that apply to my installation of the Dynon SkyView on the RV 12 aircraft project, this is because I had not previously purchased the D180 EFIS kit.

Step 5: Find the WH-RV12-Headset wiring harness routed up through the Panel Base comprised of two four conductor shielded wires WH-RV194 and WH-RZ195. Cut off any connectors leaving as much wire as possible.

Builder's note: It isn't list in the plans but RZ194 is from the pilots side and RZ-195 is for the Co-pilot side. This information was found on one of the Vans Aircraft forums at VansAirforce.com.



Crimp the WHT/BLK shield wire coming from WH-RZ194 and WH-RZ195 into one end of a splice. Find the WH-RZ944 (WHT/BLK) wire coming from the WH-00026 Option Conversion Harness, strip then double this wire over and crimp the doubled wire into the other end of the splice. See figure 2 on page 42D-20 of the RV-12 plans by Van's Aircraft.



Crimp the (WHT/GRN) conductor wire coming from WH-R194 and WH-RZ195 into one end of a splice. FInd the WH-RZ941 (WHT/GRN) wire coming from the option conversion harness, strip then double this wire over and crimp it into the other end of the splice.

Strip the ends of the (WHT/ORG), (WHT) and (WHT/BLU) wires coming from the WH-RZ942(WHT) and WH-RZ943 (WHT) three conductor shielded wires in the option conversion harness. Crimp these wires to the remaining wires coming from the headset wiring harness.



Builder's note: I put heat shrink over the bundle of connectors to keep things clean.



Builder's note: After inserting the wires from the new harness into the WH-00026 OPTION and AUTOPILOT sub-d connectors as shown in figure 2 on page 42D-20 I moved on to step 6.

Step 6: Tie-wrap the wires from Step 5 to the wires coming from the backshells at the junction of the WH-00026 Option Conversion harness and the WH-RV12-OPTIONAL.



This completes page 42D-20.

Reference: page 42D-21

Step 1: Find the wires that were routed from the WH-00026 Option Conversion Harness and WH-00036 Tunnel Conversion Harness through the F-1203A Bulkhead.

Step 2: Route the WH-P325 (WHT/RED) wire along the path of the ES RS 279-374 Phone Cable as describled on page 31-03 to the location of the ELT.



That is the last two steps to complete page 42D-21. Next time will be a continuation of the wiring conversion for the Dynon Skyveiw EFIS in the RV12 airplane.
