Spent the past two days gaining some ground with the control stick wiring & also struggling through several setbacks.
To utilize the 9-pin Dsubs I am finding it difficult to stuff everything safely within the confided area. Freedom of movement with zero chance of obstruction is essential within this space & I now understand why Vans uses the small Molex connectors here. In the end, I may be going back to that. However, I still have a few ideas to experiment with.
