Pixhawk4 to RPI cable missing how to connect the two?

Cable that allows connecting RPI GPIO to one of Tele ports of Pixhawk4 is missing. How are people connecting these two? Is there an aftermarket cable I can buy?

Obviously, I don’t want to use USB for actual flight.

I made my own by chopping up a 6-way cable and soldering the jumper leads. It shouldn’t take you too long.

Yeah, that’s what I also had to do. I’m running into mavlink heartbeat issue, but that’s another problem entirely.
