There is no NEED to connect to a mobo ARGB header you don't have, and certainly no need to adapt a plain RGB header output for connection to the Controller box. The L-Connect software tool uses that USB connection to communicate control of both the fan motors and the lights, and you use that tool to set your display preferences and fan speeds. You must connect to the Controller a cable for power from a SATA output from the PSU, and a cable to a mobo USB2 header. All the fans connect to each other in a slide-together mechanism to create an electrical daisy chain for both fan motors and lights. You mount the Controller module in your case and connect to that the lighting cable from it to the first fan. OP, you already HAVE the controller you need!! Wait a minute! I just realized from OP's last post: OP has a 3-pack of Lian Li fans WITH a CONTROLLER that is managed through their L-Connect software tool.

I will try to contact that maker and get the facts. However, I am not yet sure the stories I heard are true. I have been told of such a device from a third-party accessory maker that you can buy without changing your mobo. You need an actual ARGB controller for that type of signal. So when you use a signal translator box, the ARGB lights can be fed the proper signals to generate all the displays a PLAIN RGB system could do, but it will never get signals to generate the fancier things that ARGB lights can do when fed by an ARGB Controller.

Hence the mobo 4-pin plain RGB header and its Controller does NOT know how to send out signals that its intended lighting device cannot generate, anyway. As you are aware, a plain RGB system cannot generate many of the fancy multi-colour displays you can get from ARGB - things like a static rainbow, or even a rainbow chasing itself down the light strip. HOWEVER, there is a big limit that is important to you.

There are a few ARGB Controllers and converters like CountMike has linked to above, and they CAN convert from the 12 VDC 4-pin plain RGB signal system to proper signals and power for a ARGB system.
