It's been years since I've done more than device updates or key moves, my last JP1.x cable failed and needs to be replaced. I would like to confirm before I go through the effort, the following cable is the correct choice as a JP1.x cable for use with OCAP Atlas remotes correct?

I'm planning on using "AN EASIER WAY TO BUILD YOUR OWN JP1.2/3 (FLASH) INTERFACE" by Tommy Tyler as the wiring reference. Any comments or suggestions would be appreciated.

That cable should work fine.

Confirmed:
https://www.amazon.com/gp/product/B014GZTCC6/ works great.
The connector/cable wire colors:
2/Yellow
3/Black
4/Green
6/White
Connector pins 1 & 5 are unused
Another Harmony remote goes unsold.
@mdavej, Thanks for the confirmation.
Another FTDI module source

Confirmed that the FT232RL FTDI module from TEMU is another viable source for a working interface cable. A TEMU search for "FT232RL" finds various vendors/prices. The board is a mini USB female to male header pins and through hole solder pads for the remote connections. I used TEMU's DuPont 40 pin female to female breadboard cable kit to make up the remote-side plug. RTS requires either adding a pin or soldering to through hole pad on the board.
Connections to the remote pins below:
Pin 2 RTS
Pin 3 GND
Pin 4 TXd
Pin 6 RXd
