Tonight I connected the stick grips to the wiring loom and the TCW Safety Trim and TCW Intellligent Flap Controller. Everything works as it should, except I had the copilot comm wires triggering the pilot mike and I had interrupted the copilot flap up wire instead of the ground. That meant the copilot could select flap down with the stick disabled, so I reassigned the pinout and everything now works as it should.
