I'm just sharing a project that I put together for myself, as I thought others might be able to get some use out of it. It's a board to give priority to the left trim switches (so the pilot can override inputs from the right seat passenger). It's a very small board that fits inside a 9-position D-Sub backshell. The assembled module, with mating connector, weighs 1.3 oz. See the attached PDF document for details. Links for circuit boards and parts are in the PDF.
It's a pretty easy build, even for a novice at soldering; all parts are through-hole. A few notes about assembly:
1. The relay and five diodes have a stripe at one end. Match the stripe on each component to the one printed on the circuit board at its location.
2. The board fits between the two rows of solder cups on the D-Sub connector. It's a bit of a tight fit, so it takes a little wiggling to get it in place and properly aligned. Once that's done, solder the connector's cups to the pads on the board.
3. The backshell enclosure has one side that's slightly deeper than the other. Put the board into the backshell with the components facing the deeper side.

Here is another way to override copilot's trim switches.
