Step 2 should say..... Insert the wire labeled "Tab Up" into the 37-pin D-sub Pin 32. Then insert the remaining wire into Pin 31.

EDIT
The above is valid for an RV-12 that does not have a SV knobs module or G3X with autopilot module (either of which also has control of pitch trim)
These cases are still being investigated.
I had to reverse the wires when doing the PAP checks, set up the trim for t/o, etc....later I followed the install wiring instructions for the a/p and knob panels and didn't have any problems, the airplane auto-trims fine and manually trims fine as well FWIW.

Ran into this also. Swapped the wires. Works correct now. I have the SV AV knobs and the setup readme eludes the direction is configurable. Haven't had the chance to test it yet since I need the.dfg file.

Default Yes wiring instructions are wrong

Yes , I too discovered there is a trim motor wiring error in the plans. I installed the Dynon AP Panel during the avionics install and wanted to verify the wiring was correct after inserting the trim motor wires into the fuselage connector but prior to closing up the connector .... so I would not need to open up the connector to make changes later.

When installing the Dynon AP Panel I wrote up a detailed report on my construction Blog of the trim motor's wiring error in the plans which can be seen at the following link:

Happy Building,

Default trim 31B-04

Scott in post #19, 11-24-2015, you state that it was confirmed that DWG 31B-04 is not correct. I can not find any Van's update under Service Bulletins, Notifications, or Revisions and Changes. Where else can I look for a revision of page 31b-04 and fig.!?
