Re: 2022 Icon programming cable
Yes. I only use 3 wires. See the picture I attached. Ignore the red wire. This is a special cable I made for a Bluetooth adapter that needs the power. You don't.
This view is the backside of the connector as if you were looking into it when plugged into the cart. The white wire should be connected to the tx pin on your USB serial adapter. The yellow wire should be connected to the rx pin on the adapter. Make sure it is in 3.3 v mode. Also make sure you have the correct drivers installed and you have chosen the correct com port.
