DIY Evolution Golf Cart - Diagnostic and Tuning USB Cable

Tired of overpriced diagnostic cables? I was too.

Most USB programming cables for golf carts cost $125–$250, and I had a hard time even finding one. So I dug into how they actually work — and it turns out they’re just basic RS-232 serial with a common 4-pin ATX-style connector.
